Projects:Delta printer
We got donated a FLSUN Delta Kossel. It starts up, but the heated bed seems to be not reqignised in the software. So it needs a new marlin firmware and calibration.
Hardware
- Stepper motors: SL42STH40-1684A
- Controller: mks base v1.5 board
- Power supply: S-200-12 with 12V 16.7A output
Measurements
delta diagonal rod: 218mm
delta smooth rod offset: 215-50=165mm
delta effector offset: 34,1mm
delta radius: 109,3mm
delta carriage offset: 32mm (off 31,5mm)
| Stepper motor setting | value |
|---|---|
| Result | 80.0 |
| Resolution | 12.5micron |
| Teeth | 20 |
| Stepping | 1/16th |
| Belt | 2mm |
Software
Using proterface, we discovered the original firmware:

Slicer:
prusaslicer could work, not tested yet.
Software calibration:
- drive it using the command: g1 x0 y0 z9
