The "Blue" pins are the control lines into the stepper driver, ie step direction enable and gnd. You cannot directly plug a second stepper motor in there. Are you using both E0 and E1? if not you can...

Yes, I tried this also.... still don't solve the problem. I'll try with a smaller gear in diameter. I heard that a smaller gear have more power torque. We'll see.....

Did you check the temperature of your hotend while you are printing? Is it constant and is the duty cycle well below 100%? If the heating cartridge of the hotend is running at its limit, after some...

Well.... my hotend temperature is surprisingly good. I mean I don't have devitations bigger than 1 degree Celsius and PID calibration was done two times at 240 degrees. If I extrude in the air when...
View ArticleRe: Extruding problems
The duty cycle is the percentage of time the heating is switched on. In Marlin, it is usually a value between 0 for no heating and 127 (or 255) for full heating. In Pronterface (which I use here) I...
View ArticleRe: connecting second z-stepper-motor
Hi Dust! Thanks a lot for your reply! I have tried that, and it doesn't work. I assume the reason for why it doesn't work is that I have 2 z stepper motors, but not 2 z stepper motor drivers. And i...

Why don't you solder the two steppers together? Parallel connection would be the easiest, but series connection is better for the driver. Parallel: black to black green to green etc... Series: black1...

So I made some experiments. I printed the same part at 0.06mm layer high with 60mm/sec print speed and 80mm/sec infill speed and the print was wonderful. Same thing for 0.1 mm high at 60mm/sec print...

Did test. Timer0 really overflows millions of times. Lucky probably nobody uses this option.

Using RC8 with AUTO_BED_LEVELING_BILINEAR enabled. Documentation says that you can override number of points to probe with G29 X Y, or G29 P. Neither command works for me. It still always probes the...

The other settings are exactly the same. The only settings I change when i print for 0.06 and 0.1 are printing speed and infill speed. Just these two. And I posted them above: ,, I printed the same...

Good Day, My printer is as follows: one print head, with two independent extruders/hotends, each with it's own Bowden stepper motor. I have the second extruder (E1) servo actuated, so I move it to...

Thanks. Clarifications: 1) in this case, it's not the head that I need to control position of, but the bed Z-axis. (unsure if this is materially different) 2) would software_endstops "permanently"...

You should declare the grid bigger than you intend to ever use. And you can over ride that size and use less points.
