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
