3d Laser Printer

MikolkaPow

Friends, I
build the powdered printer.

The laser
works fine only mode - Laser

But now it
is not included second extruder motor connector for leveling each layer of
powder.

The code
that you offered to me earlier for the control shaft through the extruder
motor. works fine mode only - FFF

T1

G92 E0

M302 S1;
allow cold extrusion

G1 E-100
F3000

G1 E0
F3000; back to origin

M302 S0

T0

 

----------------------------------

Here the
firmware 

Video:

mode fff 

mode Laser

How can I run it all together at the same time and the laser engine and a second extruder connected to the shaft  ?

Your laser video is private, but you already said the solution - switch printing mode. Just uploaded new dev version that wait for end of moves when switching modes, which is important in your case. New code would be

M451 ; FFF mode for shaft

T1

G92 E0

M302 S1;
allow cold extrusion

G1 E-100
F3000

G1 E0
F3000; back to origin

M302 S0

M452 ; Back to laser mode
T0

The problem is quite simple - in laser mode we interpret E moves as laser on during move and not as motor move. I guess you used that fact already to use simple slicer output.

I am grateful for the correct code! The mode switches and the device is moving correctly.

I would like to clarify donations are accepted only through pay pal? Are there any alternative payment systems?

For simple donations yes, works best across all countries.

If we speak about a better sum you can mail us for IBAN banking number, but that generally complicates bookkeeping.
