Commands are sent incorrectly #321

Closed nfrik closed 1 year ago

nfrik commented 1 year ago

Describe the bug The order of commands is incorrect. Either every 2nd one is omitted or the order is reversed.

To Reproduce Steps to reproduce the behavior:

  1. Generate text with G-Code creation and start plotting while looking at the real-time status report on the COM port

Expected behavior

  1. Every command should be sent in the order of appearance in the gcode file

I assume you connected "Marlin" instead of a grbl-controller. Probably the first user. The problem is: to get actual position from Marlin you have to send a "real" command M114, which also generates a "ok", this confuses my buffers... I will have a look to fix that.

I can't see the problem with my Mega 2560 with Marlin 2.1.2 (just controller without real hardware), but found perhaps a point to fix. Please try https://github.com/svenhb/GRBL-Plotter/blob/master/GRBL-Plotter_1_6_8_3_Setup.exe

This worked perfectly, thank you!

Good to hear, thanks for testing. Further feedback for usage with Marlin is welcome :-)
