Configuring my A Axis

On the second page, choose modify an existing config, when you press forward it will open "open file" window, chose the working config with .pncconf extension. On the next sreen change the name of the machine and choose XYZA, mm or inch, then click forward until you get to the Mesa setup page, there should already be tabs for connectors, so on one of those tabs add another stepgen or PWM for the A axis. Press forward untill you get to the setup for the A axis, set it there as you need it and forward to save.
Let me know if i made a mess.

Well, I'm on hiatus for a bit and will have to come back to this.

After having moved motors, my G540 has decided to persistently illuminate its fault light... I'm going with 'infant mortality' until a better explanation comes along. I've had the board here since early 2016, but it's just now that I've had space and time to get on with setup, so it's only been powered for perhaps a couple of days in total.

Tried basic stuff like disconnecting everything, but that didn't change anything. Used Gecko's video to open it up and look for fried chips, but nothing I can see.

Anyway... I have an email into their support address to see if they'll support the board, given the situation.

Gonna have to come back to this when I have a working controller board...

Thanks so much for the support, folks. I'll be back with updates when my lights are green again.

Does the G540 have a switch to enable or disable charge pump?
Move that and test again.

Tom,

Yep. Tried that, no joy.

But...between Gecko's troubleshooting video and an email from one of their support techs, my motors are moving again. Basically just took it apart, powered up the G540's motherboard (green!), added stuff back (stayed green!), and voila! Back to moving motors. No idea what changed, apart from takeapart and gradually reassemble, but it works. Wired the same, switches the same...ah, well...mysteries of life.

Anyway, back to the subject at hand...my A axis now works!

Using Modify to ADD a new axis did NOT work for me. I think I did indeed forget to specify XYZA (vs. XYZ) when I ran the wizard the second time, despite getting the pin mapping right later. Anyway, Modify did NOT let me advance to configuration for the "A" axis after selecting XYZA, and instead threw errors when I tried. I can post a picture of the error page, if someone wants it.

Gave it a couple of tries before giving up on that and just doing a fresh config, which worked fine.

So I think I'm through the all-axes-moving 'gate', and it's on to the next challenge - trying to do something useful with them!

Thanks again for your help with this!

Nice, glad you got it working, i was wondering what is going on as i could not figure it out.
Thank you for reporting back.
