topic_solved z axis not working no movement at all
Looking for more help. I have a buffalo cnc router running duet2 wifi and my z axis wont move. I have movement in y and x axis. I am just testing out the connections and making sure all axis move. for some reason z is not. I have rewired and checked all connections again still no movement on z so i changed the stepper motors over and plugged the z axis motor into x and the motor moves so, that says to me that the wiring is ok, the motor is ok, so must be a config problem? could anyone help please
post you config.g
i assume there is no error in the console
you have the jumpers on the secondary z header if only using one z motor?

Looks okay, so unless the jumpers are missing, the simple solution could be to use the 5th driver for Z;
M569 P2 S0 ; Drive 2 goes forwards M569 P3 S1 ; Drive 3 goes forwards M584 X0 Y1:3 Z2 ; Apply drive mapping to axes
M569 P4 S0 ; Drive 2 goes forwards M569 P3 S1 ; Drive 3 goes forwards M584 X0 Y1:3 Z4 ; Apply drive mapping to axes
and connect z motor to E1 motor output (making sure to only connect and disconnect motors with the power off)
Fantastic. Thank you so much, that has worked. I just know i gonna have more question. T
hanks guys and girls
(If its a new board you might want to determined if the Z driver has failed and have it replaced under warranty - and use E1 while you wait)
That i did think about but i know the company that supplied me with machine and card has gone under due to covid-19 thats what his email said. so my next question is do i need to change anything so my limit switches will work on z axis?
Sorry to hear about that, hopefully the E1 driver will not give you any trouble.
As for the Z endstop, you don't need to move/change anything for that.
(In fact, unless you're running RepRapFirmware 3.x you can't change it)
ok don't have to change anything form limit switches thats cool. Next problem. when i go to home X i get a 5mm movement from z then a 5 mm movement from X, the same with Y axis a 5mm movement from Z then 5 mm movement from Y, and when homing Z just a 5mm movement. Any help please

thats controlled by the homeall.g, homex.g, homey.g and homez.g files.
its normal to raise the z before homing x and y to avoid dragging on any stock if present.
but you shoud get more than 5mm on x and y, they should move to the endstop and stop; odds are endstops are inverted?
maybe this helps?
When and where did you purchase the board? If it was from an authorized dealer who is no longer around we would still honor the 6 month warranty.
it was bought from a company called Buffalo cnc on 19th august 2020. It is a router that come as a flat pack with a duet2 wifi board.
I'm unable to find Buffalo CNC on the authorized reseller list.
Do you have a link to their website? If it still exists?
Can you post a photo of the board?
I believe buffalo cnc are part of ooznest. Here is a picture of our board.
is this an official board or will i need to buy a new one please??
Sorry I missed your post with the photo, checking now.
@Ryan-Lock recognise this board?

Thanks for tagging me @T3P3Tony. I can confirm Buffalo CNC are Not related to Ooznest in any way. The connectors on that Duet have a yellow tint, ours do not look like that.
Thanks for the confirmation Ryan.
@kesser71 Can you provide full photos of both sides of the board?
Thank you guys for looking into this for me. I was lead to believe this was part of ooznest my apologies to Ryan. Here is a photo of the back of this board and now seeing the small print i fear that this is not an official one. If i need to purchase one i will do, where do i get them from? Are they are avalible? and how much are they.
its a clone. the text at the bottom has to be included on a clone.
