So I built the frame for this and have it partially setup. Assembling the Lowrider the x zip tie clamp snapped off on me when I stuck the zip tie in there, must have had an issue on that layer when printing. I ordered more of the red PETG that I printed this with to print that part. I was able to rig it with a zip tie directly to the exposed tube, and worked fine to set up and test. Everything went well except for an issue I had on my z axis which made a wobbly mess out of the coupler. Re ordered a six pack of those in case this happens again. So my z is not working at the moment. But I got it all setup before it did that. All the things I ordered were supposed to be here yesterday now it says Wednesday / Thursday… Top off the day or two of Reprinting / printing the clamp/ vac duct I am designing for my router. Current progress sorry about mess finishing the build on my a/c closet and washer dryer counter top…
It’s working great with pen attached just no z so you see the travel lines .
Now I don’t understand why the z axis keeps going beyond the max limits I set in GRBL . It was zeroed out at the bottom , I went up and it popped off the rails even tho a max was set in GRBL causing the coupler to bend and get out of whack, I know I should have done it incrementally but I noobed on it and paid the price of having to wait to finish the build and buy $6 couplers.

It kept going / running even beyond 270Mm
I was doing it in cnc.js just hitting the +z … yeah kinda ridiculous at like 50mm increments. It was zeroed at the bottom.
Also I haven’t built the legs for this thing yet because I’m not sure weather to keep it stationary or put on casters, or figure out a way to be able to make it go diagonal for storage when not in use… I have a makeshift bar/ outdoor kitchen which I was originally going to beef up With more support at the edge and screw down the floating edges to level. That’s where I originally had in mind for this. Then I built the full size 4x8 version to have the capability to build all the cabinets / entertainment system for my house, then deconstruct / shorten pipe to fit on the bar outside , or turn into mpcnc. Pain to move this frame with one person but do able , you think that bar with the added post on edge would be enough to support / keep the frame which is much bigger then it’s current size ?
