Figured it be good to create a topic for Bug Reports so anybody that experiences any issues they can post here for help rather then the Sale topics

Most of these bugs are now fixed in realtime firmware update 1.4.9. We’re going to close this thread for now. If you experience any bugs in 1.4.9 or later, please send an email to support@realtimecnc.com for the quickest resolution, or, create a new thread in the Realtime controller bug & Software…

So far the things that i have encountered so far is When probing for x,y,z it wont transfer into the work coords section The xbox style controller can be super flakey and just randomly start and stop working The unit will randomly freeze which requires a reboot The E Stop button is very clunky and…

If you can post up videos of each bug, it would be helpful!

My controller keeps switching the units on the main screen to mm even though it is set to imperial in the config menu.

are you using a mm post processor? WHen is it switching? Can you catch it switching on video and post it up there?

Mine does it occasionally on bootup but all you have to do is hit the the MM/ Inch button on top left of homescreen and it swaps back.

The setting in the CONFIG menu is for the bootup units only. Running programs with G20 and G21 will change the current units to either inches (G20) or mm (G21).

No I am not. I have shut off the controller and rebooted it 10 times in a row. It was 50?50 MM/in. Not program was loaded. Just selecting shutdown on the HMI and restarting it.

I am aware that I can change it. My point is I should not have to.

It is not booting up in the correct units. I shutdown and restarted the HMI 10 times. It was 50/50 mm/in.

If it changed units on boot up and you home the machine does it travel at the same speed? With the Masso controller base units are mm but it converts so you don’t home your machine at 1000 inches per minute instead of 1000 mm per minute as an example
