Alright I need help Im starting to throw stuff. The Z axis wont lower after performing a g29. It just starts printing in the air at the height of the endstop tripping. I had it running perfectly and then I started touching files and messed it up. I have my offset set to -9.2 like i had it before and i have the min software endstops set to false. Im still fairly new at this and thought I had a decent understanding but im lost at this point. I can post my config H or wouldnt mind seeing someones. (Im almost positive it has something to do with some endstop setting but who knows) At the moment Im using mechanical switch probe but ill be switching this week when i get the inductive sensor parts in. Appreciate any help.

Your Z-offset should never be more than -1.0, and ideally should be below -0.5. Manually move the probe to a spot where it falls within that threshold.

Tonight was such a perfect, calming, Bob Ross-esque experience. I had to go to an xmas party hosted by a friend with a gluten allergy, and I thought it would be fun to print him this item on thingiverse as a gift. First print, after a week of printing Ninjaflex and Taulman Bridge (compounded with about 80 prints since I replaced the sheet of BuildTak) made some permanent marks/problems on my build surface, it was all just messy. I took the aluminum pate off and carefully applied a new layer of BuildTak, and had a very satisfying first print:



Doesn't it just look so clean and crisp?

Anyway, the party was convienent as the hosts live two blocks away, so when I came home I decided to print sonnylowe's Y-carriage pieces, and this is what it looks like so far:




My autolevel height is perfectly calibrated, my speed is as high as it can be without mucking up the print, and my extrusion is perfectly calibrated. With all that, and a virgin build plate, there's nothing better, right? smileys with beer

What aluminum print bed are folks using with an inductive sensor? Is there an aluminum surface that can be added to the top of the MK2B heat bed (instead of the glass), or are people replacing the heat bed altogether? I'm going to add the proximity sensor. Tired of constantly adjusting my print bed alignment...

I just use a 8x8 inch aluminum plate I got for 13 bucks. This one

I printed your filament bearing holder-thingy last week, I see since then you removed the pieces I ended up snipping off smiling smiley

Thanks so much for your help.

I tried doing what you told me, got a dmm, followed exact instructions, set it to continuity tester mode, touched the 2 leads together and heard a beep meaning the dmm is working, but I get no results when I touch each of the probes to each wire and the other probe to the the prongs. I only get a result when I switch the mode from continuity to resistance and all 3 wires give me values for the right prong and nothing else. Don't know what I'm doing wrong.

That looks pretty good! Does it stay fairly rigid and flat? Also, any problems getting the MK2B heat bed to keep it above 100 deg for ABS?

Not sure what you are doing wrong, but here is a pretty good video that does a step-by-step. Video. The video starts at where he does the cord, but it would be good to go back to the start of it and watch the entire video since it has a lot of good information for beginners.

The plate is about 3mm thick so it has almost no flex to it. The plate I received was not entirely flat on one side, but the unevenness is within fractions of a mm. I just turn the plate onto the side that had the least curve after putting on the binder clips and it works very well. I only print with pla right now, so I have not tried going to 80c.

Thanks Mach!

Anyone else placing a 3mm aluminum plate on top of their MK2B heatbed? Any issues staying above 100 degC? I think I'm going to jump on it unless anyone has an alternative.

Nvm it works now! Thanks again,

Also to anyone else on this forum, Im in config mode now. Both my z motors turn but the threaded rods dont move, they kind of like stutter as if something is blocking their movement. Any tips?

You either have too much load from something being misaligned or you need to adjust the driver current.

I had the 3mm aluminum bed over my MK2B heater, I never got it over 85C...I ran PID and it heated more quickly but still struggled to go past 85C. Could be something in my setup that's wrong...I'm not sure. Either way I printed ABS at 85C with no problem...I do print on Kapton though...

I might be going back to glass and a different sensor, if so I'll have this Build Plate and two sensors up for grabs...

How long do the BuildTak build plates last...I'm using Katon right now but was thinking about a switch!?!?

Thanks,

My first sheet lasted probably about two months, the second sheet (the one just removed) lasted a little over a month, but only because Ninjaflex can be a pain to remove if the first layer is printed too close. And I'd say I average about an houring of printing each day.

Are you talking about the voltage for the steppers? There are little pots on the steppers, use the ceramic screwdriver do you don't fry anything.

My top 2 motors turn but the threaded rod doesn't move, it gets stuck and starts stuttering as if something is stopping it, so i was wondering if I needed more current.

They turn but the threaded rod doesn't move? I am guessing you mean they turn when they are not connected to the threaded rods through the couplings, right? If that is the case, did you disconnect the motors from the threaded rods and see if the threaded rods turn freely by hand when they are not coupled?

BTW: Are running a Servo/Micro Switch setup or Proximity Sensor for your auto leveling? If it's a servo/micro setup do you mind sharing you config-h file?

I am getting some odd lines in my print and it seems as though my extruder is not smooth(stock extruder/hot end). In my other printers, my extruder turns at a smooth consistent pace when doing infill or long perimeters. With my Folger Tech, it looks jerky. What should the voltage be on the stepper driver pots? I tried adjusting them, but it did not seem to help.

I am running therippa's Marlin from his sig, with the e-steps adjusted for my filament.
