Carbide Motion stop prompt to flash mcu

Hello,

I’ve had a Shapeoko 3 for quite some time and I have normally used bCNC for control. I’m donating the machine to a school in need and helping set it up for them. I’d like for them to use Carbide Motion for ease of user experience.

The problem is CM asks to flash it before letting me control. I don’t want CM to flash as the end stops/steppers are wired up differently than stock so the bitmap CM puts causes the machine to home incorrectly and Y step bits incorrectly.

Is that possible to bypass?

I believe so — just don’t do the Download of settings — if that is required, then you will need to do this in two stages:

  • send configuration to Grbl as part of setting up the machine
  • adjust Grbl configuration using the MDI or some third-party tool

Once the configuration has been sent at least once CM should be accepting of whatever is set up on a given machine.

I’ll have to check again when I get home. Last time it wouldn’t let me check the SO3 without flashing

Once it’s been set up once, it should allow going through the Setup Wizard w/o downloading the Grbl configuration.

Since this is a custom machine would it be hard to put it back to stock configuration. The people you are giving it to will change personnel over time and may lose your custom setup. So could you just put it back to its original configuration for the ease of the student running it in the future? The staff and students could just run CM.

Well it’s too late now. Someone just picked up the machine. I told them to call support and when they do before they do anything instruct support to have them list the configuration. I also gave them my info, so we will see how it goes. I’m excited to see it go to a place that will get some use out of it. The school is smaller and they have access to a desktop shopbot once every three years as it rotates schools. Having a permanent CNC should give the kids plenty of learning opportunities.
