GRBL 1.1 and Carbide Motion 4

Rolling back to 0.9 is no longer supported, but the bulk of this post is being left in place for reference. Re-flash First, download a utility for this (see below for further documentation and an alternative using the SDK) see: Flashing Grbl to an Arduino · gnea/grbl Wiki · GitHub Hex files are no longer available When you launch the utility, Choose atmega328 UNO as the target, 115200 as the baud rate, and the attached hex file (click the button with the three dots to navigate to where you sa…

on your sixth bullet item:
Once you do that, open a log in Carbide Motion (in the settings screen)
what version are you referring to V4 or V3.

Use the one appropriate to the version of Grbl just installed:

• Grbl 0.9: CM3
• Grbl 1.1: CM4

If I use the uploaded and select the hex file in the drop box listed first will I be back at .9? Or maybe more simply is the first hex file link grbl .9?

Grbl 0.9 is available from: https://www.dropbox.com/s/5ey4rbk7l1596pe/grbl.hex?dl=0

Grbl 1.1 is at: http://carbide3d.com/dl/v4/grbl.hex

So I connected to the shapeoko controller via usb / printer cable and opened the uploader put the settings as you mentioned atmega328 etc selected the the hex file to upload but I still show grbl 1.1 when open CM3 or 4. Shouldn’t it say .9?

If flashing were successful, yes.

Usually reflashing works. If it doesn’t, there are a bunch of possible causes — saw your ticket in the support queue and we’ll get this sorted out as quickly as we can.

FWIW, my understanding is the developer of Grbl recommends reflashing by using the Arduino IDE and recompiling.
