So many have seen my posts, a few have offered suggestions and I have gotten closer... So, I tried to do the shield again, and the first layer cut, great, the 2nd layer was off a little on the Y AND X! I then ran a 50mm test box, using the caliper it was off a little, OK, easy fix, used the calc. from here made the adjustments. They came up as 50.22 and 50.21...really can't get better than that. So new piece of wood, tried cutting again, and the first layer, perfect, 2nd layer off again.... I even made triple sure to secure the wood in case of movement, no way it moved. not to be off in the exact same way/spot again. Pics below.. Using aspire 8.5, the tool path shows it as looking perfect so I don't think it is in the G code. anyone care to try it with an 1/8" ball and 10"x10" stock? (I can attach the g code I am using for testing) At this point I don't think it is my build. But obviously something is wrong. It even threw my zero point WAY off, pic below as well, it was the corner and moved A ALOT.

If something is wrong, we will take care of it. It could be a faulty part, but usually it is not.
Sometimes this happens when a set screw is loose. The motor spins the pulley doesn't. Is that part okay?
Also, please post stuff like this in the support forum vs projects.

Well I already tightened all the set screws, in the post 'will this cut' that turned out to be an issue so I tightened them all...but off on both the X and Y though? (After posting this going to double check, never can be too cautious) I know you will take care of it, it's just frustrating trying to nail down why it keeps losing zero. I am not asking for anything new just yet, I will try any suggestion. I made sure no screws were hanging below holding it up. if I spin a wheel the assembly moves and doesn't slip, it cuts the 50mm square almost perfect and returns to zero from that.

Does it do this with just g code from aspire? What post processor are you using there? What if you run the "sample" g code file in the quick start guide at www.millrightcnc.com/resourcesIt sounds like you are trying to do some checking, which I certainly appreciate. I very much want you to be running trouble free so I'll be sure to see this through with you. Please run the file in that quick start guide and let's see what happens. We'll go from there.

It cut it. Returned to zero. Using UGS-platform. Tried using bCNC but was a little difficult to want to spend figuring it out last night.
I have only used Easel and Aspire. Easel is too easy and larger or complex designs can't be done or will cost for the pro version.

Are your belts tight enough? I've had belt skips here and there and it does this same thing.. Usually it happens when I'm trying to be to aggressive with the machine. To deep of passes or to fast feed rate (I'm impatient). Slowing things down has helped dramatically.. As well as tightening the belts. One or two belt tooth skips can throw things way out of whack..

Thought of that last time, I loosened the Y motor mount, place shims top and bottom and retightened, so it is tight. The pass is with a new ball end mill, about 1/8" deep and speed of 35 I believe it was so if that is aggressive I want a refund! hahaha (kidding!) I watch it cut the entire time. I see no slipping or stalling or chunking (like in the video from the last post). Trying to convert the EPS file to a DXF an see if I can figure out how to import and carve in Fusion with it. In Aspire I use GRBL-GCODE to save so it should be fine

Can't imagine it could be Aspire causing the problem... I've run tons of stuff out of Aspire and my M3... at 100+ipm. Everything from simple shape cutouts to full on 2.5D Gotta be something simple going on. Not an expert by any means, but I can open and look at the Aspire file if you care to share (I have 8.5). It's to cold in the garage to really do much cutting these days or I'd try it out and see what happens :/ For post processor I've been using the "Grbl(inch)(*.gcode)" one which sounds like you're doing the same..

It is a couple posts up in a zip. Yeah, made sure I used the inch one, I never did learn metric.... Thanks!

Got that one, but can you send the actual .crv3d file from Aspire? The raw Gcode is a bit above my pay grade

Was just about to do that... File was too big even zipped (I have many toolpaths for different cuts and things i was trying) here is a 1drive link 1drv.ms/u/s!AnxTbPmDOiWMkxpA1q6bDC3eVVH0 Now the file I am using is actually 3 toolpaths saved as 1 file. doubt that is an issue but could be the problem? I check marked USMCpocketball largepocketflatend (which is now a ball, just didn't change toolpath name) USMCballpocket Then hit save visible tool paths. I am going to eliminate the obvious now that I thin about it and just print the Largepocketflatend path, that is the one in the images that you see messing up. Make sure it is not confusing all the paths.

I would absolutely try separating the tool paths and running one at a time just to see. I've never combined them into one file even if the bit is the same. Simple enough to just load the next file and hit go.. You did a good job on that file.. My limited knowledge can't see anything glaringly obvious wrong with it. But again, I"m not any sort of expert.

It is cutting now, almost done with the first pass so should now in a few minutes

OK so no... After it does the first layer circle it does a cleanup arc around the circle, as it closes on the bottom part it is way off again. however the machine returned to zero this time. Tell your weatherman to warm it up out there so you can run my gcode and see if it is my machine or something with aspire!
