gSender errors z-axis

After loading program file and zeroing all axis I try to run program and z-axis rapidly goes to plus max.

@Harris52 Welcome to the group, Brian.

I have moved your topic out of the gSender suggestion category.

Members here will need much more information before they are able to help you.

  1. What machine are you running?
  2. What software did you use to create the gcode?
  3. What post processor did you use to create the gcode?
  4. If you are running a Sienci machine, what controller are you using?
  5. How did you set the axes zeroes?
  6. Do you have limit switches installed?
  7. Does this problem exist for all files?

Sorry, E-mail from Forum telling me I was accepted, went to SPAM.

  1. Longmill MK2 48x30
  2. Aspire 12
  3. Grbl (in.)
  4. LongBoard
  5. Auto-Zero Plate
  6. no Limit Switches
  7. Just started using Aspire and haven’t went to another carve since this all happened. So, no idea if it’s happening on all files
