Re: individual calibration for dual extruders with Marlin - 9 years ago
Thanks I will try that next. I find it so odd that there is no individual calibration built in , there is for every other axis why not these two ?by freeform - Developers
Re: individual calibration for dual extruders with Marlin - 9 years ago
ok by sending Gcode programing code to the printer I can get it to work T0 is at E94 and T1 needs E10.25 to calibrate in .... BUT the change effects BOTH extruders regardless if T0 or T1 is chosen ! argh ! Why is there such a difference in the E factor is there an error in the Marlin code that sets the T1 at a different rate ? I have found others with this same issue using different boardsby freeform - Developers
dual extruder problem - 9 years ago
I have recently installed dual extruders. have MKS Base v1.1 board and using Marlin Firmware. have everything working except E1 extrudes about 10mm instead of 1mm . E0 works fine. I can't seem to get any help on how to fix the firmware so I can calibrate the extruders independantly, so was hoping someone had another suggestion to fix this problem. I can swap extruder positions and the problby freeform - General
Re: individual calibration for dual extruders with Marlin - 9 years ago
Thanks olaf. i have tried that mod also and write to board then reboot printer each time. Just dont get it. why is the firmware written to not allow calibrating the second extruder to begin with? where is the function in the firmware stored that designated (defines) the parameters ? should be n easy fix to extend the default axis routine to include one more variable !by freeform - Developers
Re: individual calibration for dual extruders with Marlin - 9 years ago
tries adding to DEFAULT_AXIS_STEPS_PER_UNIT in Configuration.h and it does nothing. need to find out where DEFAULT_AXIS_STEPS_PER_UNIT parent routine is written and alter it there so it will read the 5th input. "M92 overrides the firmware settings, so I'm surprised it did nothing. You sent T1 first then M92?" yes i did .. not sure what is going on but it does not change no matter what I have tby freeform - Developers
Re: individual calibration for dual extruders with Marlin - 9 years ago
I just tried it in repetier and it did not change anything seems like firmware is overriding it ?? where in marlin is the code for DEFAULT_AXIS_STEPS_PER_UNIT ? should be able to re write that process to allow for more parameters ??by freeform - Developers
Re: individual calibration for dual extruders with Marlin - 9 years ago
no I haven't. Trying to do it in the firmware so I do not have to mess with it every time I use the printer. how can I write that into Marlin to burn into the firmware ?by freeform - Developers
individual calibration for dual extruders with Marlin - 9 years ago
Hello, I have just added dual extruder to printer using MKS Base v1.1 board (ramps compatible) and Marlin Firmware. Have got everything working except canot figure out how to calibrate each extruder seperately, right now E1 tries to spit 10mm of filiment instead of 1 but E0 works fine. would also like to be able to calibrate each one for different materials and tip size. How do I code in aby freeform - Developers
