Thanks for the drilling cycle you added for grbl, but... #67

I am from China and I am a cnc fan. Thank you very much for your Candle. He is very good (I really hate the interface of MACH3, it is complicated and ugly), and thank you very much for the drilling cycle you added for grbl, (I know ug can The drilling cycle is converted to a movement composed of g1), but in the standard industrial cnc system, it is usually after a G83 command, and other identical G83s will be omitted, and only the X and Y coordinates will be written. If you send this code to grbl An error will be reported, ERROR: The G code command is missing a required value word. (This article was translated by Google. Since I am not a professional programmer like you, I have no ability to modify him.) Sample code: G98 G83 X0. Y0. Z-20. R3. F300. Q2.1251 X4.739 X19.183 Y-3.87 X17.689 Y-7.477 X15.313 Y-10.574 X12.216 Y-12.95 X8.61 Y-14.444 X4.739 Y-14.953 X0.869 Y-14.444 X-2.737 Y-12.95 X-5.834 Y-10.574 bbb aaa

Hello, in grbl you have to specify the g-code in every line. Just sending positon values doesn't work.

hankecnc commented 3 years ago

您好， 在 grbl 中，您必须在每一行中指定 g 代码。仅发送位置值是行不通的。

G1 X50.5 Y50.5 X49.5 Y49.5 X50. Y48. X52. Y52. This is not the case. Codes like this are very common in my work. The first line has been given G1, and the latter is omitted.

I used grbl here before, he can perfectly support such code, https://github.com/robomechs/6-AXIS-USBCNC-GRBL

I want to run this version of yours for my machine, but this problem cannot be solved

Schildkroet commented 3 years ago

This behaviour is not supported for drilling cycles. You have to send the whole command in absolute mode for every hole

hankecnc commented 3 years ago

钻孔循环不支持此行为。您必须以绝对模式为每个孔发送整个命令

But even G1, G2, and G3 do not support this

This is grbl USBCNC, the same code, can run normally

Can you send the complete gcode file?

Like i said, you have to send G83 for every hole

就像我说的，你必须为每个洞发送 G83

Thank you, I think I can preprocess the G code on the host computer to solve it. You are a good person, and your code is very clean and beautiful.
