$4ma is set to X because we are trying to run dual X. It’s a machine we built ourselves. Initially we only had a single X motor but due to racking we’re trying to move to dual motors. But, as the title of this post, Motor 4 isn’t cooperating.

$1tr=3.89 is correct. We went with dual Chinese ball screws on the X axis so they don’t match the lead screws we have on the Y and Z.

X > Y is because of where we have the computer/chilipeppr in relation to the machine. It just makes more sense for us; less mental gymnastics is a Good Thing.

The Z Limit switch does exist. We’ve had too many problems with random plunges and broken bits with TinyG and Fusion 360 to risk running without it.

Currently all the jogging works fine.

Currently we use both CoolTerm and Chilipeppr on an iMac. We started off with a MS Surface 4 tablet running Chilipeppr but had a lot of trouble with it so we switched to the iMac. In retrospect, I don’t think it was the Surface tablet that was the problem. Chilipeppr itself seems to have a lot of trouble with TinyG. Basically the TinyG stops responding to any commands so we are continually having to cut the power to the board, restore power and then reconnect Chilipeppr. CoolTerm doesn’t appear to have this same problem but due to how tedious entering commands is we haven’t used it nearly as much.

All in all, we have not had a good time with TinyG and are seriously regretting not having simply gone with a Mega 2560 and RAMPS 1.4.

We double checked and have both motors set to 1.8. The behavior is still the same as described.

The microstepping is also set to x8 for both.

I’m trying to get a video of it to provide more insight but I’m leaning to hardware issues.
