3D Printing Forum

I have a Geeetech A20M. i had a print come up off the bed and push my 3d touch out of alignment. Have not had a chance to work on it until this week (been sitting about a year.) i updated the GT2560 board firmware to 2.3.2 (has the 3d touch menus) when I do the offset where i sheet of paper drags under the nozzle and same the offset, it repeats fine. BUT when i try to print one of my saved files the print head is way to high like 1mm or more off the bed. i can stop the print and check the height by moving the z axis and it is at the correct height ( i also changed the nozzle (which is not as long/tall as the original)
Please help

info:
Marlin 1.1.18
GT2560 v4.1 firmware 2.3.2
Geeetech A20M

I enable baby stepping for just this reason.
When selecting a model to print baby steps allows me to move the nozzle into place while the skirt is printing.
The newer version of marlin have a feature called Z-Probe offset wizard this allow the offset to be fine tuned quickly before printing.

Thank you I will see about upgrading my marlin too then. I will have to look it up because i know i have to change a file so the information is correct for my printer. Any insight you can offer me to do the upgrade?

I downloaded the new marlin software (more than one actually) took the files form the geeetech config files off of github for my printer. downloaded vscode and the suggested plugin from the video. tried to compile and it failed. tried with 2 other versions all failed so i downloaded the marlin plugin and it also failed to compile. any suggestions i can take pics if you want to see what it says on the screen

Post the errors that were displayed when you complied the firmware.

these errors or pretty much the same except for the version of firmware (yes i did use the correct geeetech files from the examples folder per version)

sorry the pics are in reverse order

Interesting the preview is upside down but displays fine when clicked.

I commend you, I hate compiling firmware. I just haven't kept up with all the changes and software apps needed to compile and create the fw

it has ALWAYS given me problems lol. i was guessing i would have to get the mew marlin firmware. I noticed the marlin firmware says mega2560 v3 my 2560 board is v4 according to the printer display (cant compile to send to the printer just asking

I finally got it to build ya!! now wont upload giving me access denied (first error) many more any hints?

Have you looked through this?

not that one. i have a gt2560v4 board i am hoping the mega2560 build will work for it

thank you i got it on my printer the bl touch is not working or have it in the firm ware BUT i know it can be turned on in the firmware got to find it recompile and resend it
thank you

got everything running. new/old issue. i set the offset for print height on the nozzle, but when i print it is to low to the bed. no matter what i make the offset the print head has to be manually raised during print start or its to low. also if (when in manual mode) when z is at 0.000 i can not move below that even though i am not at the hard/soft stop
