That would be awesome. Thank you!!!
Got the Z leveled to .0575mm. I think I’m gonna call that good lol

I feel your pain! I did that about a hundred times I think - (into a foam bed though) until I woke up and found a couple of bits of timber that limited the depth of plunge before I could hit the stop!

I’ve never had a machine do that. So it’s new to me. Only thing I can figure is it was a mix of headless and screen use (hard to break old habits) so I’m not sure if that was throwing it off or what
In other news. Working on traming. Found a piece of copper wire that fit in a collet. Used the touch plate and ran it out both sides. Came up with .44875mm over a 370mm span. The surfacing bit I usually use is 32mm. I don’t know the math to figure out if that’s off far enough to matter. Anyone know how to figure that out??
Ok wait maybe I do know the math. I took the .44875 divided by the 370mm span and got .00121283783. Took that times the 32mm bit I plan to use and got .03881********
So if I did that right over the full width of the bit I’m only of .039mm. That’s about the thickness of a hair. And I usually only run a 15-17mm stepover on the bit. So that would only be .018 at 15mm. Will I even notice that??? Or should I apply some tape on the low side??

Sure thing. Shared .dxf and .EstlCam .e10 files at v1engineering-mods/lowrider3/squaring at main · aaronse/v1engineering-mods · GitHub, just engraves simple 1mm deep 3mm width (1/8" bit) corners outside 24"x16" framing square. I engraved these to help tweak and double check machine was square enough to cut side panels for my MP3DP v4. Hope that helps!

Ok I wound up tightening the mount just a touch on the top of the low side. Doing that got me to .16875 across 370mm. So if my math is mathing correctly that’s .01459 across 32mm bit. Or .00684 across a 15mm stepover.
Unless I am just completely screwing this math up (always a strong possibility) I think this thing is pretty well trammed in for what I need. Side to side anyways. I didn’t look at front to back lol

Well I’ve had enough of the hot garage today. Unless I wake up to objections over my crude tramming numbers I plan to attempt to surface it in the morning. After surfacing I’m hoping to try out @azab2c framing square technique and if it passes that I’m going to get fancy with @jamiek ruler scripts. Hoping with an extremely flat bed I will be able to make some nice crisp lines and have it look nice. That is until I forget to carry the one and end up driving the bit way too far into it LOL.
In other news by tomorrow evening I should have the last of the needed parts to repair my full sheet LR3 “Fat Albert” and hoping to go pick up a sheet of aluminum tomorrow if the boss allows it. When I made this one I added an extra brace in the X beam. Between that and the 1/4" aluminum struts I cant bow it pushing down on it as hard as I can. It doesn’t take much effort at all to flex the full sheet beam. Hoping by adding an additional brace (or 2) and stepping up to the 1/4" aluminum struts I will gain a lot of stiffness in that beam as well. Wish I had time/ability to design up a cool looking front strut to make it stand out more. But oh well. I’m happy with the ones I’ve been running. And already have the paint colors to match!

My simple dxf/e10 will engrave the surface, which you probably won’t want to do after surfacing since you’re wanting to do ruler markings as well.
So, maybe just Jamie’s squaring script with a pen. Or…
Just remembered, Ryan shared a squaring video/gcode that I planned to try out next time I need to square…

Well she is running!!! I can see the lines but cant feel them when I run my fingers across. Cant wait to see how it looks after putting the ruler marks on it. I’m guessing that would best be done with a fine tip pen vs a normal sharpie. Wonder if the Wife will notice if I steal another of her fine tip sharpies LOL. Will post pics after the ruler marks are there.

So are you doing magnet and washer or magnet to magnet?
Thank you @DougJoseph Wouldn’t be anything without all the amazing help from here!!!
Going to have to back up and punt on the ruler. The pen kept getting hung up on the mount and would mess spots. Stopped it and removed the mount, then put 3 1/4" flat washers behind the pen mount and that freed it up a lot. but that also moved the pen slightly and messed it all up. Going to take a break and cool off for a few. Then going to go through the tramming process again and run a .1 or .2 surface on it to get rid of those marks and then run it again. the washers really freed up the pen movement so i think it will come out great this time around.
What do y’all usually run for the pen on Z? I set it with a piece of paper then ran -.5 on @jamiek script. Is that normal or should I be doing something different???
Magnet on the base mount and a 1 1/4" washer on the mobile mount. 2 magnets were too thick and it wouldn’t set right. Almost went back an printed your acorn style mount before I realize (and actually read instead of just looking at the pretty pictures) that he was running a washer. Quick trip to Ace Hardware and I was in business.
I’m really hoping something comes of the Probe and ill get a lot more use out of the mount than just the occasional Pen. Well I’ll get more anyways once I figure out how to do large scale vinyl on it LOL. Son and my Ex-Father-in-Law have a race car that needs more vinyl work than my Wife’s cricut can handle LOL

Sounds about right.
Cool!
I definitely want to explore both laser-added mount and probe-added mount.

I will add mention of this in the Printables listing for the pen mount!

I was looking at it and there really isn’t any way to add spacing with the way it prints. But the washers was a simple add on. And you adding it to printables then anyone already sourcing the other needed hardware could get that at the same time. It made a big difference for sure.

After changing out the pen mount today I needed to go though traming the spindle again. Figured I would take a pic of my setup. I have no idea if this is right or wrong but so far it seems to be working lol. Took a few more tries tonight and ended up having to put a piece of tape on the top of the x+ side but after doing that it’s even closer than I had it yesterday. .00011 per mm. So total for my 32mm bit is .00368. Can’t complain with that.
