Marlin 1.1.9 for I3 A Pro (with lead screw upgrade) by flat-jack
Posted: Wed Dec 19, 2018 2:13 am
Would like to post my Marlin Firmware 1.1.9 for Geeetech i3 A Pro. I got some good printing results with it. Linear advanced is not active! Manual bedleveling is activated.
But before you use it - read the following text carefully!
I replaced the old stepperdrivers (A4988) for x,y,z axis with TMC2208. If you have the old ones change following lines in configuration.h back to:
also change the following lines back to:
I also experienced "homing-errors" with the standart A4988 stepperdrivers. Upgrading to TMC2208 solved the problem.
When using A4988 stepper drivers and having problems with homing your printer try:
I use a custom cooling fan and set my own KP, KI, KD settings for 195°C. Cooling Fan: https://www.thingiverse.com/thing:2329594. So maybe go back to default:
I calibrated my extruder to value of 95 steps/mm. So don't forget to adjust to your own value.
Okay here is a little Update:
Wrote a new temptable for the thermistor: https://www.geeetech.com/10pcs-100kohm- ... p-632.html
Saved it under Preset 66-> Geeetech Extruder + Heated Bed (R25=100kOhm, beta25=3950, 4.7 kOhm pull-up)
maybe go back to default:
Maybe someone finds this helpful.
