Found Override Feed has some problems? #120

Closed viewsat closed 6 years ago

viewsat commented 6 years ago

When the send G-code, the Override Feed down to 10%, and then adjust the Feed up 100% did not respond, it seems that there are some problems. I have also tested other Gcode sender programs to work properly.

I use the G-code: I found that F is set to 100 when the error occurs. G21 F100 G1X200 G1Y150 G1Z50 G1X0 G1Y0 G1Z0 G1X200 G1Y150 G1Z50 G1X0 G1Y0 G1Z0 M30

I don't have a physical machine at present but the Status reports from Grbl definitely show the FS part of the response changing as Feed Override is changed up and down. I tested with Grbl 1.1e so not the latest

The following two pictures of my Grbl settings, when x or y or z [accel] is set to 150 ($ 120 or $ 121 or 122 = 150). Send gcode F = 100, Override Feed down to 10, There will be an error. I use Grbl-Panel to test Grbl 1.1e & 1.1f results all have the same error. I use candle 1.1.7 gcode sender test no error occurred.

I use the G-code: G21 F100 G1X200 G1Y150 G1Z50 G1X0 G1Y0 G1Z0 G1X200 G1Y150 G1Z50 G1X0 G1Y0 G1Z0 M30
