A10M Massive Under Extrusion Issue

[gwood1000]

Hello,

A while ago a coworker asked me to look at his Geetech A10M because he could not get it to print. I have been working on it for several weeks and have just recently gotten it to the point where I can print this benchy.

Best Print

In total, I have upgraded the ptfe tubing, replaced the hotend assembly entirely, updated the firmware, increased the e-steps on both extruder motors, increased the voltage on both (extruder) stepper drivers to 1.1V from 0.9V and reduced the speed to 60% and increased flow to 200%.

I am at a loss for what to do next. I have had this printer for much too long and would like to return it as soon as possible; preferably in working order.

Any thoughts would be greatly appreciated.

Hi, You can try
1. The printing speed is reduced (30-60mm/s);
2. Check if the nozzle is clogged, the temperature of the hot end can be heated to 200 °,
and the consumables can be manually pushed to check whether the material is discharged;
3. Check if the step value is 430.
4.level the hotbed.

I hope this can help you.
