Print is Starting to high!!! January 12, 2017 07:27PM |
Registered: 7 years ago Posts: 12 |
I have a Hictop Prusa i3 running marlin firmware. So far i have tried cura 15.04.6 and slic3r 1.2.9 and i keep getting the same results. I have the bed leveled and it homes perfectly fine but as soon as the print starts it raises somewhere about 0.3mm above the bed. with slic3r i set a z offset of -0.3 and the first layer prints the way it should ( i think) but then it jumps up to high for the next layer. ive calibrated, looked at the configuration file, looked at gcodes. idk what to do anymore and ive looked everywhere. if someone could help that would be awesome. ive attached my config.h and config_adv.h files. if needed i can take screen shots of my settings or a video of what is happening.

level bed to 0.1mm with z at home leave z offset zero check filament and nozzle diameter then set layer height to 0.2mm done in the slicer program and print a cube if this fails you need to calibrate z axis steps/mm for the threaded lead screw done in configuration slic3r has built in calculator

Just re-read your 1st post , umm If you have 0.3 set as your layer height in the slicer, then yes it will raise Z too 0.3 at start of print, it is not supposed to start print at Z0.Quote
as soon as the print starts it raises somewhere about 0.3mm above the bed
If 1st layer is not sticking to the bed then you either have your Z0 slightly too high or 1st layer extrusion in silcer set to low.

Hmm,i see what you mean, from the video that looks like about a 2mm jump from 1st to 2nd layer.
If you home Z and then send a G1 Z20 F2000 how far does Z actually move.
Allso can you check what Z steps you have set in the eeprom (config menu in repetier host)
Hard to see on the video, but is that a M8 threaded ror or is it a M8 lead screw on the Z axis. if it is a lead screw then it is probably a 4 start screw and your Z steps/mm should be 400 not 1250

when i type in that command my end of my nozzle is at about 125mm above the bed.
not really sure about the z-axis threads this is a link to the exact printer i bought [www.amazon.com]

Yes that line is correct, change the 2560 to 400.
However the old setting will be used from the eeprom, so either run the eeprom clear sketch in arduino/files/examples before you upload the firmware
or after uploading new firmware,use your printing host (repetier/pronterface) and send a
M502
M500
those 2 codes will read the config data and store it too eeprom
* If Z now move a bit slow, a few lines below you will find Default max feedrate increase the 3 to 40

thank you so much! i was finally to print for the first time! but now i had a thermal runaway... i had this problem before when i was trying to get a print i would let it run and see what was happening. it gets up to the 210 degrees like it should then about 10 min into the print or sometime after the first few layers my printer will start decreasing in temp and give me a false error. i have already went back in the code and up't the degrees and time it takes to throw the code. any other suggestions?

Try running an auto PID tune on the hot end
[reprap.org]
Make sure you dont have a fan pointed at the bottom of the hot end directly cooling the block.
