I noticed all my problems are coming from the LongBoard outputting voltage despite being turned off. So if do M03 (clockwise, sets to “LOW”) it will read 0.43v. Is there something I am doing wrong here or is my board defective? It is a LongBoard 1. 4.3
Connecting the LongBoard to my HuanYang VFD has input terminals that connect to a digital ground that will read 1 if any voltage >0 is detected. These toggle the Start / Stop, Forward / Reverse, etc. commands on the VFD and will not work if the LongBoard is still outputting voltage.
If this cannot be fixed, this can probably be solved using some relays for 1v or something, but I would rather not have to.
When I use M03 (clockwise) the user guide says it is supposed to set the voltage to HIGH which I assume they just mean “On” and it is 5v (multimeter measuring 4.91v). However M03 is setting it to “LOW” and M04 is setting it to “HIGH” so things are backwards. I have a Longboard Rev. 1.4.3.
Is this supposed to be like this?
