Solution Found: "Error: Feed rate has not yet been set or is undefined"

natedgreat · August 11, 2019, 1:58am

Hi everyone. I’m receiving an error that’s stumped me and I can’t figure it out. I’m receiving “Error (1): GRBL ERROR: Feed rate has not yet been set or is undefined.”

After honing, going to xy position and zeroing out, I run the file and the (Dewalt) router will proceed to go to the cut start position then stop and throw the error.

I’m not sure why that’s the case as I can’t think of anything that’s change since last using the machine.

I use Aspire software and the feed rate for the .25 EM is set to 70 IPM. I can’t think of anywhere else to set the feed rate? Any ideas why I’m receiving this error?

Thank you!

What post processor did you use?

natedgreat · August 11, 2019, 3:04am

Sorry I left that out. Post Processor is Shapeoko (inch) (*.gcode).

Not sure if this helps, but i did run a log within Carbide Motion right before I hit Run:

There’s a G1 Z move with no feedrate.
Can you share your gCode?

natedgreat · August 11, 2019, 3:30am

Absolutely. Here’s the Plain Text Ouptut Of the first Toolpath

Post Processor = ‘Text Output Arcs {mm} {*.txt}’

All values are in mm, feedrates in mm/min

Material Info

X Min = 0.000 Y Min = 0.000 Z Min = -12.700
X Max = 609.600 Y Max = 457.200 Z Max = 0.000

X Length = (609.600)
Y Length = (457.200)
Z Length = (12.700)

Z Origin for Material = Material Surface
XY Origin for Material = Bottom Left Corner
XY Origin Position = X:0.000, Y:0.000

Home Position

X = 0.00000 Y = 0.00000 Z = 20.32000

Safe Z = 5.080

Tools used in order of use

  Tool: 1 = #46248 Upcut End Mill {0.25 Inch}

Toolpaths output in order they are output

  Toolpath: Profile 1

First Tool

Tool Number = 1
Tool Name = ‘#46248 Upcut End Mill {0.25 Inch}’

Cutting Speeds

Cut Feed Rate = 1778 mm/min
Plunge Rate = 1778 mm/min
Spindle Speed = 18000 r.p.m

Toolpath File Information

Toolpath Name = ‘Profile 1’
Toolpath Pathname = ‘E:\Completed\compost\error.txt’
Toolpath File Name = ‘error’
Toolpath File Directory = ‘E:\Completed\compost’
Toolpath Extension = ‘.txt’
Toolpath Notes = ‘’

Date Toolpath Created = Saturday August 10 2019
Time Toolpath Created = 10:20 PM

Design File Information

File Name = ‘turbine - Copy’
File Pathname = ‘*\Compost\turbine.crv3d’
File Notes = ‘’

Feed Rate Change - F3556.0 mm/min

Initial Rapid Move from home or toolchange position

X: 37.13126 Y: 61.06723 Z: 5.08000 Home = X:0.00000 Y:0.00000 Z:20.32000

Feed Rate Change - F1778.0 mm/min

First Plunge Move

X: 37.13126 Y: 61.06723 Z: -6.54050

Linear Feed Move

X: 36.22354 Y: 61.68423 Z: -6.54050

X: 35.35300 Y: 62.34352 Z: -6.54050

Solution Found:
I think somehow my file might have been corrupted. I decided to create a new file project, import the vectors from the previous, load same EM specs and toolpaths and its running fine on the machine now. Somewhere in between the Z feedrate wasn’t coded even though Aspire had feedrates and displayed the project correctly.
