I get it. Yes I did upgrade all the controller to the high power units. I also updated the limit switching to Merkel button type.
The machine has homed perfect since then. Anything I can do to help you let me know.

I think Iām the only one who has been public about swapping controllers.
I didnāt swap controls because CutControl didnāt work. It did everything that Langmuir said it would do. I did it because Iām a tinkerer and wanted more control over my machine than CutControl could give me. I wanted more automation in tool changing, support for a 4th axis, and eventual support for an automatic tool changer that Iād like to add.
CutControl is an appliance. It doesnāt allow for much modification, but I didnāt have the kind of problems that you are having.
Have you tried using different PCs? If so the next thing that Iād check is if you are having power supply issues ā maybe you could watch the 36v power supply output under high load to see if the voltage drops.

Alex your another that I am thankful for all your help. There is another guy on here that was going to convert the controller as well. I cant image you doing this for no good reason.
I did not see a difference with another PC. I donāt have an issue homing I have an issue with homing not being remembered. Several times I have homed it, went to zero the tool on the tool setter and get an error message stating I need to first home the machine which I just did 2m ago so I home it again, go to set the tool and that message comes back. Sometimes this has happened 3-4 times before it takes.
I hit the safety limits and the entire program locks up only to have to reboot the program not the computer. There are others on here that have this same issue and Langmuir admits its a program issue so I know its not me.
I found the new upgraded (supposedly) drivers that Langmuir sells that should be here soon and I am crossing my fingers they help with the missing step issue. I havenāt had any other axis lose work zero since I put a new controller in nor had to rehome 15 times. 
Could the voltage be dropping?? Maybe, I appreciate the advise and once I pull this box again I will see if I can record it. For now I have a 6K piece of crap taking up space that I get to rebuild.
If I had your abilities I would build my own that worked. I built a 4x10 CNC router and I donāt have an ounce of problems I have like with this but I didnāt use .50 cent crap either.
Would you tell me what reconfiguring a new controller did for you?? Is it feasible to convert to Mach somehow??
I have another thread about it (that is near the top of the thread stack today). I converted because I wanted more direct control over how the software works (Iām a software engineer in my day job). I used LinuxCNC because Iām more comfortable and familiar with it, but documented enough that anyone comfortable with wiring CNC machines should be able to pick the control of their choice.

New to this, so Hope my request seem legitimate. How about a canned circle/hole cutting program with adjustable diameter and depth. Include a bit size choice. (If possible, a part of the pgm for clear out a stepped / recess hole in a plate) parameters from min to max hole size with XY being center or edge of hole. Also a square/rectangle program with min and max parameters as well, with center XY and corner choice. Including bit size choice as well.
I think newbies like me sometimes just want to be able to throw a piece of metal on the machine and cut a 2.187 hole in a 1/4" thick blank or cut a 5.062" x 7.1875 rectangle in a 3/8" aluminum plate. I think it will help get some newbies like myself going and help with understanding the benefits of learning fusion 360. Maybe there is already a program to do this out there I donāt know about?

Another feature Iād love - find center of the part for zero (x and Y). I mean, I can do math, manual jog etc, but there are advantages if your blank isnāt perfect

I think one important update would be Backlash Compensation. Not sure how hard is to implement, but is invaluable to get precision cuts.

Would love exactly this feature its super useful
Cutter compensation seems like a critical capability of a CNC controller. I keep opening CC thinking that I must be missing it.

I would like to have them add a āsend to backā button to the screen. A useful option for me due to the way I modified my door. Others may have their own reason to have a second button to make a quick move to a desired position.

Backlash compensation is ridiculously easy to implement. Hope they include at some point but they still havenāt written full G code interpretation.
Displaying the dimensions of a probe routine at the bottom of the screen would be helpful.
Additional X and Y probe routines for finding the middle of a feature(2 x and y routines for internal and external features).
Has anyone measured the backlash? On a raw stepper motor to ball screw motion stage, with preloaded ball screws, backlash should be negligible. There will be backlash if the tension nut hasnāt been fully dialed in, but otherwise, Iād think it would be minimal.
There is risk of lift on z, but the spindle is incredibly heavy and backlash wouldnāt help here since itās a chaotic error.
Backlash compensation is more typical for servo stages with a gear reduction head.
Even preloaded ball nuts will have backlash at some point. Iām not saying itās necessary for the MR-1, only that if it were needed it could easily be implemented. My Fadal had backlash compensation built into the control, with preloaded ball-nuts. The screws are shimmed for bearing preload instead of by tightening a nyloc hex nut. Weāre also talking about compensation for <.0001" though. Those kinds of numbers are well beyond what the MR-1 was built to maintain so is not a fair comparison.
Now that you mention it, I will see if I can get some numbers on my machine and Iāll post them here, for those that are interested. I amā¦now. 
Keyboard shortcuts for send to front and auto toolset without warnings would be really handy for production runs
@Snowfarmer69 check out what I just started using AutoHotKey. You can set the hotkeys to whatever you want, change where it clicks for your, and even make it do multiple things off one click.
Iām still working on getting it all built, but this is what I whipped up this AM.

I donāt recall if this was mentioned yet. -
Add Z retraction prior to moving to the tool setter XY position when doing the tool setter probe routine.
Iām certain many have broken probes by now.

This.
To make matters worse, the Z Up key on the pendant also doubles as the āacknowledgementā key when you send to the tool setter.
Basically, you probe the part, hit calibrate, then the saftey message comes up. You realize you are too low and instinctively hit āZ Upā and then crash the probe.

So, for example, if you need to increase the size of a profiled bore you need to re-post the program?
Yep. Poor manās cutter compensation- Mill the feature, measure, adjust the model/CAM, repost.
