Anything easier than Skienforge?

Yeah my printer is going super slow in printing.

advice? or other Gcode generators? I used 3dtoolchain.com made by a techzone programmer, but its been down for 2 days and thats unreliable, so i need to learn skienforge or any other option.

Any settings advice for Techzone Huxley model? Thanks all.

Which version of SF? How slow is it going? Have you changed the Feed Rate variable on the Speed tab?

SF 38, because i didnt update my firmware yet. Its going REALLY slow. like 1mm a second .

I think I did change that number. Is that the variable which will speed it up?

If you are using SF38, then you need to play with the Feedrate and Flowrate settings on the Speed tab. If you use SF40+ and modify your E_STEPS_PER_MM setting in your firmware, you can just set both values to the same setting to control speed.

The Feedrate controls the speed of the head over the bed, in mm per second. Flowrate affects the speed at which the extruder pushes out filament.

Another setting to check is in the limit tab, make sure the values there make sense. This limits the speed of your axis if they end up going too fast.

i am getting the same issue but now it only dose it to me when it is trying to extrude, i have looked over my options more than a few times, but i can never seem to find the setting that i need to change.

@owism and @dissidence: what are your feed and flow rate settings? Start with a feed rate of 20 mm/s or lower.

Hey Brnrd, Here it is:
Feed rate: 30
flow rate setting: 236
Orbital feed rate/operating feed rate: 2.08
travel feed rate: 20
