You sound a lot like me. My 'go to' printer is still the 2020 i3 because it just keeps going! I have the FT5 to with the BLTOUCH, E3D, and the Titan. It also runs well but I've used it mainly to run parts that I need multiples of for orders. I made a few things that required the height given by the FT5 but mostly groups of parts. The one advantage I like with the RC8 is that it lets you reset and test the BLTOUCH right from the LCD screen. It also does mesh bed leveling for uneven glass surfaces like the borosilicate glass I use. I manually leveled for a long time but I succombed to the lure of another 'gadget', the BLTOUCH, and haven't looked back. No more leveling at all now. Plus, the real downside of the FT5 is the crappy bed so the BLTOUCH solved that problem plus I only use 3 points, as you should, to level the bed close enough.

Has anyone tried marlin 1.1.0 rc8 on their 2020 yet? Just wonder how your display looked after the update.the attached photo is how mine turned out. I just install bltouch on mine last night and decide to try out rc8 for the bltouch support. Just wondering is i missed a setting some where to for the display?

I recently downloaded 1.1.0 RC8 on my 2020 i3 and I have the normal screen. I also have the BLTOUCH installed for the last year or more. No problems. I suggest you try to download the ENTIRE RC8 again and install it all again. Maybe you somehow selected the wrong display.

I also have RC8 running on my FT5

//============================= Z Probe Options =============================
//===========================================================================
// @section probes

//
// Probe Type
// Probes are sensors/switches that are activated / deactivated before/after use.
//
// Allen Key Probes, Servo Probes, Z-Sled Probes, FIX_MOUNTED_PROBE, etc.
// You must activate one of these to use Auto Bed Leveling below.
//
// Use M851 to set the Z probe vertical offset from the nozzle. Store with M500.
//

// A Fix-Mounted Probe either doesn't deploy or needs manual deployment.
// For example an inductive probe, or a setup that uses the nozzle to probe.
// An inductive probe must be deactivated to go below
// its trigger-point if hardware endstops are active.
//#define FIX_MOUNTED_PROBE

// The BLTouch probe emulates a servo probe.
// The default connector is SERVO 0. Set Z_ENDSTOP_SERVO_NR below to override.
#define BLTOUCH

// Z Servo Probe, such as an endstop switch on a rotating arm.
//#define Z_ENDSTOP_SERVO_NR 0
//#define Z_SERVO_ANGLES {70,0} // Z Servo Deploy and Stow angles

// Enable if you have a Z probe mounted on a sled like those designed by Charles Bell.
//#define Z_PROBE_SLED
//#define SLED_DOCKING_OFFSET 5 // The extra distance the X axis must travel to pickup the sled. 0 should be fine but you can push it further if you'd like.

// Z Probe to nozzle (X,Y) offset, relative to (0, 0).
// X and Y offsets must be integers.
//
// In the following example the X and Y offsets are both positive:
// #define X_PROBE_OFFSET_FROM_EXTRUDER 10
// #define Y_PROBE_OFFSET_FROM_EXTRUDER 10
//
//    +-- BACK ---+
//    |           |
//  L |    (+) P  | R <-- probe (20,20)
//  E |           | I
//  F | (-) N (+) | G <-- nozzle (10,10)
//  T |           | H
//    |    (-)    | T
//    |           |
//    O-- FRONT --+
//  (0,0)
#define X_PROBE_OFFSET_FROM_EXTRUDER 0  // X offset: -left  +right  [of the nozzle]
#define Y_PROBE_OFFSET_FROM_EXTRUDER -20  // Y offset: -front +behind [the nozzle]
#define Z_PROBE_OFFSET_FROM_EXTRUDER 0   // Z offset: -below +above  [the nozzle]

// X and Y axis travel speed (mm/m) between probes
#define XY_PROBE_SPEED 8000
// Speed for the first approach when double-probing (with PROBE_DOUBLE_TOUCH)
#define Z_PROBE_SPEED_FAST HOMING_FEEDRATE_Z
// Speed for the "accurate" probe of each point
#define Z_PROBE_SPEED_SLOW (Z_PROBE_SPEED_FAST / 2)
// Use double touch for probing
//#define PROBE_DOUBLE_TOUCH

//
// Allen Key Probe is defined in the Delta example configurations.
//

// *** PLEASE READ ALL INSTRUCTIONS BELOW FOR SAFETY! ***
//
// To continue using the Z-min-endstop for homing, be sure to disable Z_SAFE_HOMING.
// Example: To park the head outside the bed area when homing with G28.
//
// To use a separate Z probe, your board must define a Z_MIN_PROBE_PIN.
//
// For a servo-based Z probe, you must set up servo support below, including
// NUM_SERVOS, Z_ENDSTOP_SERVO_NR and Z_SERVO_ANGLES.
//
// - RAMPS 1.3/1.4 boards may be able to use the 5V, GND, and Aux4->D32 pin.
// - Use 5V for powered (usu. inductive) sensors.
// - Otherwise connect:
//   - normally-closed switches to GND and D32.
//   - normally-open switches to 5V and D32.
//
// Normally-closed switches are advised and are the default.
//

//
// The Z_MIN_PROBE_PIN sets the Arduino pin to use. (See your board's pins file.)
// Since the RAMPS Aux4->D32 pin maps directly to the Arduino D32 pin, D32 is the
// default pin for all RAMPS-based boards. Most boards use the X_MAX_PIN by default.
// To use a different pin you can override it here.
//
// WARNING:
// Setting the wrong pin may have unexpected and potentially disastrous consequences.
// Use with caution and do your homework.
//
//#define Z_MIN_PROBE_PIN X_MAX_PIN

//
// Enable Z_MIN_PROBE_ENDSTOP to use _both_ a Z Probe and a Z-min-endstop on the same machine.
// With this option the Z_MIN_PROBE_PIN will only be used for probing, never for homing.
//
//#define Z_MIN_PROBE_ENDSTOP

// Enable Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN to use the Z_MIN_PIN for your Z_MIN_PROBE.
// The Z_MIN_PIN will then be used for both Z-homing and probing.
#define Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN

// To use a probe you must enable one of the two options above!

// Enable Z Probe Repeatability test to see how accurate your probe is
//#define Z_MIN_PROBE_REPEATABILITY_TEST

/**
 * Z probes require clearance when deploying, stowing, and moving between
 * probe points to avoid hitting the bed and other hardware.
 * Servo-mounted probes require extra space for the arm to rotate.
 * Inductive probes need space to keep from triggering early.
 *
 * Use these settings to specify the distance (mm) to raise the probe (or
 * lower the bed). The values set here apply over and above any (negative)
 * probe Z Offset set with Z_PROBE_OFFSET_FROM_EXTRUDER, M851, or the LCD.
 * Only integer values >= 1 are valid here.
 *
 * Example: `M851 Z-5` with a CLEARANCE of 4  =>  9mm from bed to nozzle.
 *     But: `M851 Z+1` with a CLEARANCE of 2  =>  2mm from bed to nozzle.
 */
#define Z_CLEARANCE_DEPLOY_PROBE   10 // Z Clearance for Deploy/Stow

// For M851 give a range for adjusting the Z probe offset
//
#define Z_PROBE_OFFSET_RANGE_MIN -20

When checking the fuses measure DC voltage across them. If you read 12 volts, they are blown. If you read 0, they are OK.

Hello,
So I got my FT 2020 i3 built and printing; however I do have a couple of issues that I am unsuccessful so far in resolving.
1. It prints in a mirrored fashion. Meaning the resulting print is that exact mirror of what the original is. I can resolve this in the Repitier Host by selecting the "mirror" button, but really would like to permanently fix it. I did some searching and found some suggestions, but no luck so far. I still have more research to do on that.

2. The more important issue that I would like to resolve is the print size. I printed the 20mm test block and the sizes are all off on all axis's. (as well as being a bit distorted on the top x-axis) I have tried adjusting the bed and nozzle temperatures as well as used different brands of filament, but no luck. This is my first experience with 3d printing so I apologize if what I ask is basic, but I have had no luck so far and am reaching out for suggestions.

My setup is as follows:
FT 2020 i3
Repitier Host w.slic3r
FT supplied firmware
Printing PLA
Bed/nozzle temp heat: 70/219 ~ 0/200

First some pictures of the print would be helpful to diagnose the issues. What firmware are you running? The beta or the orginal?
The print size can be a few things. From the e steps not calibrated correctly. Z steps also. And extrusion not calibrated right. Have you calibrated all of these? The FT settings are an ok place to start but not the final say. And do you have a cooling fan for the part while printing?

Thank you!

crumb4life,

I'm using the original firmware. Attached is a picture of my first cube with no cooling fan and the second (different file) is with a cooling fan. (I also has a problem with is printing mirrored images of the original)

The second print's X and Y axis actually measures much better, but the Z axis in about 2mm short.

I will look at what it takes to calibrate the 'e' steps next and try that.

Thanks!

So here's an update: I calibrated the extruder and the Z-axis .. That's all good, however this gets strange. I printed out a calibration cube (20x20x20) that I downloaded and it measures pretty close. I then created my own 20x20x20 cube and the measurements were much better. So it looks as if I am good to go ... so I thought ...

I created a tube (think straw) for a project that I am working on and the diameter is way off. I tried this couple of different ways: nozzle/bed heat , created in mm/in - setting the appropriate size setting on the Repitier and even checking it in another program (name escapes me).

Tonight I will try another square print and circle print to see how mush it's off.. any input is more than welcome!

Thanks again!

You should turn on line numbering in Marlin to make it easier to comment back.

Of course, first you must define your x,y, and z_PROBE_OFFSET_FROM_EXTRUDER.

Then you should take away the two \\ from //#define PROBE_DOUBLE_TOUCH

and increase #define Z_PROBE_SPEED_SLOW (Z_PROBE_SPEED_FAST / 2) to /5 so the second probe is slower and more precise.

You might want to play around with the value of these once you are up and running to save some time so the BLTOUCH doesn't go up so high between probes.>
#define Z_CLEARANCE_DEPLOY_PROBE 10 // Z Clearance for Deploy/Stow
#define Z_CLEARANCE_BETWEEN_PROBES 5 // Z Clearance between probe points

Have fun

I just finished my build and had a few questions

#1 Why is the Z carriage under the 3rd stepper driver plugged in backwards?

#2 Step 21-2 picture shows Black + Red - but reads Black - Red + which is correct?

#3 I am using the Full LCD so the firmware updater i use is FT-2020 Full LCD correct?

#4 Step 7 config manual, doesnt read Folger Tech under author mine reads author: SW & CM

#5 I get a Fatal Error on Connect, Extruder switched off MaxTemp triggerered and I cannot get it cleared. I have checked all wiring it is wired correctly.

any help to any question is greatly appreciated.

Mark,
On the Google drive link for the Folgertech 2020, under Beta Firmware there is a zip file titled FT-2020-FULL_LCD, unzip this to your pc.There will be a file called FT_2020_FULL_LCD.ino , double click this, it will open in Arduino IDE. Choose your board and COM port and upload. That is all. Close Arduino IDE your LCD will reboot with the Folgertech menu. Next proceed to Repetier for more difficult configurations. I hope this helps.

Matt

Thanks in advance for the help.

I've finished building my printer but I'm having zero luck getting it to function. I've broken this down to the following issues:

1.) When I run M119 my Y_max endstop shows Triggered 2.) None of my axis will move more than half way and Y-axis will move in one direction but not the other.

Issues I've had and resolved: 1.) Motors moving in the wrong direction - Reversed the plug for the steppers on the Ramps Board. 2.) Had my x & Y endstops wired backwards x where Y should be and vice versa.

Things I've done:

1.) Used the community build guide at: [github.com]

2.) Followed therippa's instructions and used his firmware and moved the X-endstop. [github.com]

I've tried finding a basic setup the firmware tutorial but so far I'm unsuccessful. Any advice will be appreciated.

First I had to move the x-axis endstop to the left side so that it is a MIN type as well as the others.
