Recently purchased and assemble Shapeoko 4 Standard. Assembly appears to have gone well however when I ran the first job, (simple star), the cutout on the wood was elongated…or perhaps more correct the “X” dimension was narrower than the “Y”. Wood was fully adhered to table so no movement there. Any suggestions of the cause and perhaps solutions so we can get a dimensionally correct cut?
Thanks for quick follow-up. The information provided is for a Shapeoko 3 however I have a brand new Shapeoko 4. Is process the same? Also, I question that a brand new machine and corresponding belts would have a “stretch” issue when less then 6 very small jobs have been run. Not making sense to me.
I checked tension on the belts and all three seemingly are of equal tension when trying to lift off railing. Definitely see belt lift of only a couple of mm. I did notice the travel in the x direction is slightly slower then the y though both seem to move freely when using the quick motion jogging. Resistance in the x direction I presume may be the issue…I see no obstructions though question whether the cable management is the source?
Here is an example of what is happening. This was a cut of a 3" circle. As shown it has not cut symmetrically
-I checked for squareness of the machine…ok
-drive belts are all snug with approx 2 mm lift when checking tension…
-when jogging machine…travel appears free in all directions both manually and to any of the 9 quick points.
-brand new machine with perhaps 7 minutes of run time
-checked for loose screws…none
-Set machine settings for shapeoko 4 Standard …X=445 mm, Y=445 mm Z=95 (default settings
can you upload the gcode file you used for that cut ?
if you open Carbide Motion, go to the Settings menu, click the “Show Log” button in the bottom left corner, keep the new window open on the side, then go to the “MDI” tab, and send $$ in the command line there, you should see a list of $xxx values being logged: what’s the value of $100 and $101 ?
on perhaps a related or not topic…
using the default machine settings for shapeoko 4 Standard …X=445 mm, Y=445 mm Z=95 … it seems that only half the width of the work area is being used. This is shown by using the rapid jog. This doesn’t make sense to me…
I initialized the cnc and it went to normal home position.
I went to JOG to see if there were any issues moving using Rapid Position and yikes… C is now front where roughly S was. S causes dreadful noises and cnc error messages…clearly it thinks S is off the machine bead. Turned off cnc then turn back on…no changes…something is not right
I changed back $101 = 40, re-initalized and went to Jog…things are back to pre-changes.
Also, as mentioned… only using 1/2 the work area using the default machine settings.
