Hi, thanks for an interesting piece of software :)

I have previously used Inkscape Gcode-tools to run my DIY Plotters, but there seems to be no support for that anymore.
Your GRBL-Plotter looks very promising, but I can't seem to get my plotter and the software to connect right.
I have uploaded the GRBL firmware myself (and not through the Xloader), because I need some settings changed for running a Core XY machine.
Can that be the problem?

Using GRBP-Plotter 1.5.8.0
I can connect but get no movement or control of the machine.
Tested using UGS (Universal Gcode Sender and there was no problem with moving
Also, there a red alarm button on, that I cannot remove, and get this from the "COM CNC":

[CTRL-X] reset
Form will be reduced after connecting

• RESET
  < Grbl 1.1h ['$' for help]
• Version 1.x
• Read grbl settings, hide response from '$$', '$#'
• Assume buffer size of 127 bytes

Any help would be greatly appreciated :-D

Up to now I don't have a coreXY machine, but in principle grbl should work with GBRL-Plotter...
About the Alarm - I found a bug: $X to cancel the alarm will not be sent, I fixed this....
Please check the update: https://github.com/svenhb/GRBL-Plotter/blob/master/GRBL-Plotter_1581_publish.zip

Would be nice if you could show your coreXY Hex file...
Another user has problems with v 0.9: #195

Thank you Sven, that worked perfectly :)

I've attached the hex-file I use, and I verified it by uploading it with the Xloader, and all seems fine. I have also attached the GRBL file with modifications for my system:

- Changes to config.h for running Core XY
- and defaults.h changed to fit my machine (all the things you can change in in GRBL-Plotter with "$ = ??")

There is still an issue with the Core XY setup, which will not let you home the Z-axis. It's a bit annoying, but I can live with it. (This has nothing to do with your software, it's a GRBL thing)

If you run the attached firmware on a regular XY plotter you will get som very erratic behavior, where the machine moves diagonally instead of straight.

The png is just to show, that I now get data back from the arduino, now that the alarm is turned off.

I hope it is for some use :)

Btw, I get this error message when running the setup (but it doesn't seem to affect anything?):

Thanks for the feedback,
About the installation-error: perhaps you can show the mentioned logfile: C:\Users\KPTJRN~1\AppData\Local\Temp\VSD6317.tmp\install.log

[kptjrn]

Sure, it's here

install.log

And thank you for the help :)

It seems, that some DOT.NET files were missing and the setup-tool tried to download them:

Perhaps windows tries to get the files with the next update?
Thanks for the feedback!
