Help configuring firmware of printer with dual direct extruder August 26, 2021 11:20PM |
Registered: 2 years ago Posts: 13 |
I have a core-xy that I've been trying to configure using rep rap and a duet mainboard 6hc and expansion board 3hc. I have made some progress configuring the code thus far, thanks to help from the rep rap and duet communities. Right now all of the limit switches, steppers, and dimensions are working great. So no problem homing the printer, but I haven't made any progress on the hot-end. Can someone help me build the G code for the hardware and connections described below? I have gotten started using the config tool, but I can't use this for a dual extruder head.
The picture attached is the dimensions of the print head. Below are the connections:
Primary extruder heater --> expansion board out1
Primary extruder thermistor --> expansion board temp1
Primary extruder fan --> expansion board out 7
Primary extruder --> expansion board driver1
Secondary extruder heater --> expansion board out2
Secondary extruder thermistor --> expansion board temp2
Secondary extruder fan --> expansion board out 8
Secondary extruder --> expansion board driver2
I am confident in my driver codes except the extruder drives. Limit switch and Z probe codes are configured as well. But everything regarding the hot-end is going to be off.
