Hi everyone!
I’m relatively new here and just finally got my MR-1 up and running since having it delivered. I had Langmuir Systems do the assembly before delivery. So upon running the baseplate facing program, I noticed that the y axis looks like it doesn’t go all the way to the top of the baseplate. I’ve attached a picture of the baseplate after the second surfacing.
Is there a way to get it to go further without hitting the limit?
Are you using the correct end mill for the program you selected? A 1/2 inch end mill is needed for the 1/2 tool surface program. You are using a 3/8 inch end mill with the 1/2 program.
It hard to tell your posted picture leaves to be desired.
I got my machine with one of the first batches and this might have been fixed since then. In my case I had to turn off soft limits to surface the full baseplate.
Use 1/2" end mill but run the 3/8" file… cleans up a little bit better…
Sorry about that! 1/2 inch end mill and 1/2 inch program!
So, that’s what you used, or not? Like @AlexW said, turn off the soft limits in the top right corner.
Also, I jogged the machine to the furthest it would let me until it reached a hard limit, then I manually faced the baseplate at the hard limit with the 1/2 inch end mill… it still left an edge of the baseplate up. Is there anyway to fix this? It seems like it shouldn’t have this problem…?
I went to the furthest hard limit possible and manually faced the furthest edge, still leaves part uncut
Hard limit would be crashing it to the bearing carriage. With the limit switches off can you run it into the end of travel? Nice and slooow.
Oh, interesting. Let me see about how to disable the limit switches and try it
The alternative is to get Langmuir to send you a fly-cutter mill. That would reach out past the edge. I don’t remember the exact measurement of the base plate from the front rim of the tub.
I believe it was 8- 9/16 inches. Hopefully, they will put the plate in the right place.
Click on the hamburger looking thing. Turn off the switches and hit save.
This was the absolute furthest it would go before it made too many noises lol. It’s weird because the center of the baseplate got cut, but the far back corners both barely miss it… much less now, but still just slightly.
After you tram all the axis. Get the fly-cutter they offer and we will get the fly-cutter program to run it. It will reach out past the edges. Just for haha’s
Measure the distance from the edge of the base plate to the outside edge of the front of the chip tray. It should be 8-9/16.
This will solve your problem. McMaster Carr
Reduced-Shank End Mills, 2 Flute, 11/16" Mill Diameter, 3-5/16" Overall Length
That edge won’t effect anything you plan to mill down the road. If its sharp maybe a little sanding the lip carefully. That is a 11/16 mill with a 1/2 shank for the spindle to use. I would run the same program and only take off .001 or so.

Y’know, I’ve always wondered about that. They spell that out in the assembly instructions, but that dimension didn’t work for me. I used 8-9/16 and my plate turned out to be out of my cutting parameters. Which isn’t a huge deal in the grand scheme of things, just incredibly annoying. I was thinking maybe it’s because I went from the outer front edge of the tray vs the inner edge, but nope. Had I gone from the inner it would’ve been even worse. So the back 3/4" of my plate is uncut.
Someone on here a while ago added a plate behind the standard plate and flipped the whole x axis around to cut it. You can just flip it around if you really want to get the last 3/4 of the plate.
If Langmuir assembled this unit, please email them to address this issue. I suspect that the base plate may have been installed incorrectly before the concrete was poured.
To resolve this, I recommend using the Langmuir fly cutter or a reduced shank 11/16 end mill. The fly cutter can make a cut of 1.5 inches per pass.
