    Update, I have the machine moving and responding as it should. On X & Y when I give a 12.7mm command the head mones exactly .5″ (1/2 inch). However I am still fighting this build and have a long way to go.

    I am connected to Chilipeppr and if I run the stock logo, it stacks the letters on top of each other. I wish I could find a way to post a pic here, but I just cant. I have to post a video instead. BTW I tried to change the $xvm but it didnt have any impact. I did reach out for help in another forum and he suggested it might be the Feedrate G0 set to fast and it was being skipped. Baby steps, baby steps. At this point I am thinking of buying All new steppers and starting from scratch.

    Thanks for helping me figure this stuff out
    I feel so dumb, I think $EX (flow control) was my main problem from the start. I did read the setup instructions for CoolTerm and did in-fact have CTS checked in the Options dialog of CoolTerm. But also Xon was checked, and in the board parameters it was set for $ex=1 which is xon/xoff flow control. As soon as I changed it to RTS/CTS, everything started working as It should.

    Also I used a dial indicator fo set up my strange Z axis ball screw to travel close to the correct distance.

    I also corrected X,Y and Z polarity to Positive in the right direction (right hand rule)

    Again, with a small (such as 3.175mm ) in the $1tr=3.175mm or $2tr=3.175mm , the steppers will not move at all no matter how big or small of a command for them to move example G00 x-50 or G00 x50 the motors power up ( I can hear it), but the stepper will not rotate at all. If I have a larger value $1tr= 10mm or 20mm ect, the steppers will rotate (but as you know, they move the wrong distance). My machine is all lead screw only, no pulleys)

    In the video I shared earlier, it shows that small $tr=? number, the motors wont move, but increased, they do move.

    I cant seem to post a photo here (I tried the IMG tag but the image would not display, below is a link to an image of the CoolTerm Settings

    Ill go through the settings you stated, Do a new $$ dump directly when I get home. Thx again,

    Please watch this short video to see why I am pulling my hair out. Simply changing the $1tr value to 1/2 of a set value, the motor will not even rotate. Do I need new steppers? What am I doing wrong here.

    YouTube video of the problem

    Ok, ive tried several tines to set the parameters for this old machine, but its been a fail. My machine has no pulleys, belts, or gears. Mine is all lead-screws attached fo steppers and the nuts on the lead screws are attached to each rail. When I input the correct settings based on the TPI of the lead screws the stepper motors barely move. The default 40.00mm (i think) moves the rails, but not at rhe corrwct distaces per the commands given.

    What do I do here? Do I just keep putting in various numbers then send a command and measure with a dial indicator until I get the correct output based on code sent?

    There must be something I am missing here, a multiplier that is set wrong (pulley/belt setting).

    Is there anyone here willing to speak to me directly and help me get dialed in. Id be happy to pay for your time. I just want to get setup and start cutting a few parts

    Thanks, T

    Ok, my Z axis has some strange type of lead screw that I can’t measure, however I did gather some numbers and hopefully we can figure out what the proper $3tr setting is supposed to be. By default 3tr is set at 40.mm gave a command for z to go 1” in mm (25.4), however it only traveled .142“ (3.6086 mm). Do I divide 25.4/3.6086 (7.04225mm) ill try this and see what happens) to determine what my $3tr setting is supposed to be? BTW I used a dial caliper to make the measurements,I need to go find my dial indicator to get a more accurate measurement, but I think i can get close like this.

    After looking into the MM vs Inches it seems that MM is the way to go ans just do the conversions from IN to MM

    I remapped the motors.
    Now onto the task of configuration of this unknown machine 🙂

    My lead screws are 8tpi, if 10 tpi = 0.100 per revolution then does 8tpi = 0.080 (2.032mm) per revolution?

    Also I like working in inches, so I set $GUN=0 (G20) and confirmed its what the board is set to, however it still shows 1tr m1 travel per revolution in mm not inches.

    Isn’t setting GUN=0 supposed to make everything else reflect in inches instead of mm?

    Sorry for a million questions, its been a very long time since I played with this stuff, and it’s coming back slowly.

    Looking at the wiki and actual config I think I see why I have a problem.

    1ma is set to 0 (which is X, what I want)
    2na is set to 1 (which is Y, what I want)
    3ma is set to 1 (which is Y, but I need be Z so it needs to be set to 2 for Z)

    I updated to the latest FW 440.20 0.97

    Are those the default motor mappings? Let me see if I ca. Remap Z
