Dead zones in the Y-axis

Hi

orginalFromTarget3001.ngc...................Gcode from Target 3001 - PCB
CorrectionForCarbideM-T6-tool.nc.........Carbide not support FeedRate on separate line
                                                         Carbide not support setting Z axis after change tool
gCodeVisualizationA.tiff.....................visualisation G code, error #1

IMG_1825.jpg.................................jpg -> svg -> carbide create -> carbide motion - works perfect

We have made several experiments, we wanted to exclude our mistake. G code commands we entered through the console in Carbide Motion:

Experiment #1.
G code
real positon
G1 X91.964 Y41.92
X91.964 Y41.92
G1 X93.165 Y43.121
X93.165 Y43.121
G1 X93.165 Y45.661
X93.165 Y43.121
G1 X95.139 Y47.635
X95.139 Y47.635

Experiment #2.

We changed the zero position about 5 cm on the X-axis and Y. Result is same as #1

Experiment #3.
G code
real positon
G0 X91.964 Y41.92
X91.964 Y41.92
G0 X93.165 Y43.121
X93.165 Y43.121
G0 X93.165 Y45.661
X93.165 Y45.661
G0 X95.139 Y47.635
X95.139 Y47.635

Rapid possiton works normaly

Experiment #4.
G code
real positon
G1 X95.139 Y47.635 X95.139 Y47.635
G1 X93.165 Y45.661 X93.165 Y45.661
G1 X93.165 Y43.121 X93.165 Y43.121
G1 X93.165 Y43.121 X95.139 Y47.635

Descending order works normally

Experiment #5.
G code
real positon
G1 X93.165 Y43.121 X93.165 Y43.121
G1 X93.165 Y43.121 X93.165 Y43.121
G1 X93.165 Y50.661 X93.165 Y50.661
G1 X95.139 Y47.635 X95.139 Y47.635

Jump to Y50 is possible !!

Here we have exhausted all ideas

Carbide motion...............version 359
Shapeoko XL..................version 3

Please help

backlash or insufficient tension?

Other project from carbide create works corectly

In that case, I’d suspect the endmill which you are using and the feed-speed rates.

Post those details?

G00 X93.441 Y54.91 F18.0

feed-speed 18
material: Cuprextit 200x100x1,5 / CU 1x35 um
cutter 1PC Carbide PCB Engraving Bits CNC Router Tool 10 Degree 0.1mm

we test it in material polystyrene, same result

each time you try, I got the same result with a high accuracy

Contact support@carbide3d.com — hopefully they’ll be able to work this out.
