I upgraded the ultimaker software with the default machine settings (start and end code with Marlin G code flavour) and then I installed the Marlin. I did the same with the exception that I reduced the purging and retraction by 90%. However, I did not notice any difference. The gcode is generated by me since I want to build something simple. From the Ultimaker, I need the x-y-z movement and the extrusion. Not the other features (heating etc).

Thanks @tinkergnome ! The steps are now fixed. I disabled the retraction using the command M209 S0 & changing the advanced setting in ultimaker (length & speed of retraction equal to zero) but I did not manage to disable the pre-printing (filament purge before starting the printing). I changed the machine settings by deleting the commands at the beginning and the end of the program. Then I upgraded the firmware through cura and afterwards, I installed the Marlin. However, I did not see any difference. Do you know why this is happening? Thanks a lot for your help!

Hi @tinkergnome ! I changed the software successfully! Thank you a lot! I have a couple of questions. I am trying to change the steps per unit of the extruder DEFAULT_AXIS_STEPS_PER_UNIT {80.0,80.0,200,282} However, even if I change the 282 to 0.282, I can not see any difference. Do you know why? Also, I tried to disable the heater-thermistor by set the TEMP_SENSOR_1 equal to 0. However, the heater warms according to the custom material even if in the gcode I do not set the temperature of the extruder's heater. Do you know if I can disable the heater of the extruder? Thank you in advance!

Thank you very much for your help!

Thanks a lot Didier!

Hello everyone! I am making modifications in an Ultimaker 2+ in order to build a 3D Bioprinter. I need to remove completely the heated platform but when I do it, I get error messages. Also, I have to change the height of the printing platform since when I switch on the Ultimaker my extruder (it's modified and longer) hits the platform. This is happening before the calibration of the printing platform. I was thinking that I have to make some small changes in the software of the Ultimaker but I couldn't find the software. What do you suggest? Thanks, Andi
