[gnea/grbl Issue#737] Command for R support About GRBL HAL

Issue #737 | 状态: 已关闭 | 作者: beckmx | 创建时间: 2019-10-09

Just wondering, I searched in the shapeoko forums and some say yes but not quite sure if the R command is supported by grbl. I have a piece of gcode with this command and before I send it I just want to make sure it might probably work:

“G90 G0 X0.0000 Y0.0000 Z0.8000 (Dragknife Toolpath3) T1 (Dragknife End Mill) F50.0 F20.0 S0 G0 X0.6291 Y1.4893 Z0.2000 G1 Z-0.0500 F20.0 G3 X0.3364 Y2.1962 R1.0000 F50.0 G1 Z-0.1400 G1 X7.4141 Y9.2703 G0 Z0.2000 G0 X9.7718 Y9.7373 G1 Z-0.0500 F20.0 G3 X8.3572 Y8.3234 R1.0000 F50.0 G1 Z-0.1400 G1 X1.2794 Y1.2494 G0 Z0.2000 G0 X6.0004 Y9.2749 G1 Z-0.0500 F20.0 G3 X7.4141 Y9.2740 R1.0000 F50.0 G1 Z-0.1400 G1 X10.0048 Y6.6781 G1 Z-0.0500 G2 X8.5911 Y6.6790 R1.0000 G1 Z-0.1400 G1 X2.2207 Y0.3119 G0 Z0.2000 G0 X-1.3138 Y1.5812 G1 Z-0.0500 F20.0 G3 X0.0983 Y1.5787 R1.0000 F50.0 G1 Z-0.1400 G1 X0.6582 Y1.0150 G0 Z0.2000 G0 X3.0168 Y-1.3446 G1 Z-0.0500 F20.0 G2 X1.6050 Y0.0720 R1.0000 F50.0 G1 Z-0.1400 G1 X1.0469 Y0.6300 G1 Z-0.0500 G2 X2.7540 Y-0.0771 R1.0000 G0 Z0.2000 G0 Z0.8000 G0 X0.0000 Y0.0000

yes, grbl does support radius format arcs. But it seems your code won’t run because arcs constructed incorrectly

#2 – beckmx 于 2019-10-09

do you have documentation on the syntax?

#3 – chamnit 于 2019-10-09

Yes. And don’t use R mode arcs. They are way more sensitive to numerical errors.

#4 – beckmx 于 2019-10-09

should I replace it with G91.1? that’s the default output of aspire so I am not sure what should it be

#5 – barma1ey 于 2019-10-09

the syntax is correct, but values contain numerical errors. and G91.1 command is not supported

#6 – beckmx 于 2019-10-09

For instance this line (the first appearance of the -R-)
G3 X0.3364 Y2.1962 R1.0000 F50.0
@barma1ey what are the numerical values? the decimals? (sorry for the questions)

#7 – beckmx 于 2019-10-09

@chamnit I am starting to use Aspire (https://www.vectric.com/products/aspire) but if you point me into an example I will dig in there to make the conversion

Are you using a postprocessor written for GRBL, it should be outputting your file in the correct format for GRBL.

#9 – beckmx 于 2019-10-09

@MeJasonT yeah you were right, the postprocessor option was the failure :s, now exported correctly

You are very welcome
