Hi all, My workbee1010 has been unused for a few weeks , i fired it up yesterday and its reporting a problem when trying to run g-code ALARM: 2 - G-code motion target exceeds machine travel.

Yep homing successfully, can move to and stop at all soft limits . And move to work zero position correctly. It Will run the flattening code generated by the wizard ok ,
The the file you are trying to run, is larger than These dimensions: (relative to stock placement and where you zeroed etc, the move causing the error would exceed the envelope you provided) and is thus prevented from running by: Read more here: gnea/grbl
cheers guys, seems to be related to the travel I have on my z axis , I reduced the The Safe Z or Rapid Clearance Gap and it allowed me to run the gcode. great support as all ways. thanks
You need to make it in your cam software. Potentially your post processor settings too, but hard to guess without knowing what you are using.
The changes you need to make are in Vectric when you start creating a toolpath. Not at my PC, so can't give you a screenshot, but at the bottom of the set up screen there are two settings for Z safe/retract/clearance heights (can't remember exactly what they are called) which will need to be reduced. Alex.
I had this issue trying to carve a 59mm thick piece and my Z travel is only 60mm. I change the safe z height in Vcarve to 0.5mm, recalculated the tool paths, and then it worked (with prayers to the CNC gods). Now I scale my carves so they are no thicker than 58mm. I like the extra 1 mm for the safe z height. I really need to finish my modifications with a higher Z.
Hello there, i experience the same problem like Kyrenia ALARM: 2 - G-code motion target exceeds machine travel. Machine position safely retained. Alarm may be unlocked.

Did you remember to HOME before Setting Zero? You have inverter axis - make sure your machine follows Cartesian Standards According to this your Limits are at Axis Maxima - if any of your switches are not, this needs changing 1) Make sure it jogs correctly (X+ moves too to right, Y+ moves too to back, Z+ lifts tool up) 2) Then make sure it Homes correctly 3) Then HOME 4) Then SetZero 5) Then run Soft Limits are confusing for beginners though as you need to understand Machine and Work Coordinates
I managed to make a copy of the g-code generated by Estlcam the feed for the axes is well below the set max. values for the axes in the CNC router, so I can't understand why I keep getting the error message (Project test) (Created by Estlcam version 11 build 11,244) (Machining time about 00:08:59 hours) (Required tools (MDF 18mm) G21 G90 G94 M03 S0 G00 Z3.0000 (No. 1: Uitsnijding 1) G00 X-717.5000 Y-229.5000 G00 Z0.5000 G01 Z0.0000 F200 S0 G01 Z-1.0000 G01 Y-124.5000 F250 G01 X-462.5000 G01 Y-229.5000 G01 X-717.5000 G01 Z-2.0000 F200 G01 Y-124.5000 F250 G01 X-462.5000 G01 Y-229.5000 G01 X-717.5000 G01 Z-3.0000 F200 G01 Y-124.5000 F250 G01 X-462.5000 G01 Y-229.5000 G01 X-717.5000 G00 Z3.0000 M05 M30
See above reply - Machine Coordinates come into play too (Disabling soft limits until you have a deeper understanding of the coordinate systems are always an option, otherwise work through the provided steps)
thanks for your response, yes i first go to home and then set zero i changed the invert to $3 and all axes now home to + as you describe in your comment But i stil get the alarm
And are you zeroing in the correct spot? Top Right it looks like from the hidden screenshot behind the error
Hi peter, thanks for your help, I turned off the soft limits and the CNC router is now doing a test run and seems to work fine
looks like your project 0,0 is at top right of the material. is that where you set 0,0 in Control? the project 0,0 in Estlcam is where you must set the 0,0 on the material. conventionally at bottom left, but can be centered or anywhere else you have a feature you can measure. Very important that whatever is used in the drawing must also be used on the machine.
Yes it is true that standard in Estlcam the 0 point is lower left, but you can also indicate where you want it yourself, I have therefore chosen for upper right
