80 or 160??

Synapsis

I was following the Duet WiFi – Configuration walkthrough and adjust – Part 1
when talking about the Drives they state

Steps pr mm

Since I just changed microstepping from 32 to 16, I need to change the line, where I used the M92 Gcode to define steps pr mm.

My current setting is 160 steps pr mm for XY, 800 for Z and 2050 for E:

M92 X160 Y160 Z800 E2050 ; Set steps per mm

I’ll change that to 80 steps pr mm for XY, 400 for Z and 1025 for E

M92 X80 Y80 Z400 E1025 ; Set steps per mm

Now if I use 80 i get only 1/4 of the bed . If I use 160 all is well

Is this because in that guide they are talking about a delta while I have a CoreXY?

My advice us to put the M92 command(s) to set steps/mm before the M350 command to set microstepping. Set the steps/mm in the M92 commands to the correct values for 1/16 microstepping. Then when the M350 command is executed, the steps/mm will be adjusted automatically to compensate for the change in microstepping.

Also in the giude they used M555 P1 for RepRafirmare while when I used the configratir by default is was Marlin which by you would be best?

Yes. Your XY steps/mm is probably 80 if your motors are 1.8deg/step, or 160 if they are 0.9deg/step.

Yes I have 0.96 degree motors.

Quick question, my extruder is behaving in a strange manner If like I have above if I say load filament it turns in the correct distance and the same fie unload.
but when I say extrude 5 mm it turns in the wrong direction a spits out the filament.
Now if I use S0 the the extrude turns ion the correct manner but load and unload turn in the wrong direction.
Also they turn for a long time like seconds almost and the E motors off button does not stop them.

What commands or macros are you using for load and unload filament?

The ones in the web control interface. Now I trieds to see what happemed in a print and it dose not turn at all.

Have you selected a tool (e.,g. by sending command T0) before printing or trying to extrude?

Synapsis

Correction it does turn in the print only very slowly.

No when i try the buttons I do not send any commands.

Ok if select S1 when i do a print it turns in the right direction, its the button on the interface that are not working as they should.

dc42

Let me get this clear.

If you select as tool (e.g. T0) and do a print, it extrudes correctly;
If you select the same tool T0 and then press the Extrude button on the web interface, it retracts filament instead of extruding it; and if you press Retract than it extrudes filament instead of retracting it.

Is that what you are saying?
