Recommended slicer settings for H2

[Eric Thorén]

I installed the BIQU H2 on my Ender 6 but I have some problems with extrusion.

After having changed the e steps to 932 as recommended, I measured and in fact I needed 951. Extrusion was fine during the m92, but as soon as I start a normal print the filament jams in the nozzle and extruder motor skips steps. I have tried with brass and hardened steel nozzle - same problem. I have to disassemble the whole H2 to solve the problem.

• My settings were:
• Nozzle temp 200 C
• Speed 200 mm/s
• Retraction 1 mm
• Retraction distance 1 mm

Could it be my settings? What are the recommended settings (it is my first direct drive try)?
