Very new need help with external drivers
-
i re weird and all is working now… now on the the BLtouch can you tell me the 5 pins it should be going to i cant seem to get any defant findings also in the firmware set up what option do I use?
-
all is working now but my E0 motor. it was working before the other
M584 E4 X6 Y5 Z7:8 ; Apply custom drive mapping

ok thank you for the help… last question I got BLtouch working took some digging.
how can I raise Z higher in between probs
at the end of a print it homes Xand Y but when the X end stop is hit Z goes down 10mm then the same with Y how can i stop this?

H parameter (dive height) in the M558 command.

What it does at the end of a print is determined by your slicer end gcode. So it's your slicer configuration that you need to change.

so i change this
M558 P5 X0 Y0 Z1 H5 F100 T2000
to M558 P5 X0 Y0 Z1 H10 F100 T2000
?
I have looked in the Gcode and it just had G28 X0 Y0
what it dose is raise Z 10mm homes X lowers Z 10mm the raises it then homes Y and lowers and raises Z

thanks for all your help i will be replacing more printer boards with duets no more mks!!!

1. Yes.
2. Instead of G28 X0 Y0 at the end of config.g you might want to use e.g. G0 X0 Y0 F5000. Or you might find e.g. G0 X0 Y200 more convenient.

thanks you….
can you give me some insight on right now I'm having a shifting problem Y- seems like .1mm a layer not bad so I'm thinking it in accels
M566 X50 Y50 Z12 E120 ; Set maximum instantaneous speed changes (mm/min)
-
Layer shifts are usually caused by the hot end catching on a blob or curl-up from the previous layer during a travel move. Remedies may include:
- Z hop during retraction/travel moves (practical on deltas, less practical on other architectures)
- Better print cooling to avoid the curl up, or better retraction settings to avoid the blobs
- Higher motor current
- Reduce travel move speed
However, it you are getting a layer shift at every layer, that sounds as if it is acceleration or speed related. Use the motor EMF calculator at https://configurator.reprapfirmware.org/ to check that you are not trying to make the motors move too fast and reduce top speed if necessary (M203); otherwise increase Y motor current if the Y motor is running cool, or reduce acceleration.

thank you i am working on speeds now i added a fan to the Y motor i might get a water cooling setup for it but cant seem to find many options.
