Greetings to all fellow members! I tell you my problem:
I have an hss86 driver with a 12n motor (the typical kit they sell) when it feels like it, the alarm is activated and the axis is disconnected. This can happen after 10 minutes or like this last time when the program finished and raising the Z axis has been disconnected, when this happens it makes a loud noise (as if it was skipping steps or something) the bad thing about this is that it has very little use and it seems strange to me that it fails (I have had them for years but with very little use) could this be from the motor, encoder or driver? I'm afraid to try it with another dever from another axis lest I ruin it. I have looked at the connections several times in case they are a little loose but that is not the case....

I've been looking and I don't see the HSS86 as much and it seems that they are changing it for an hbs86 or an hss86 with a display? What do you advise me? The control board is all CNCdrive.

Thanks greetings!

In the end I decided to get involved... I changed the connection of the X and Z axis motor to see if it works well and where I connect the Z motor with its encoder, it fails, the alarm LED flashes 3 times. So the driver works well (I preferred it to be the other way around, the driver is cheaper...) and the connection, the motor or the encoder fails... I'm going to keep looking.

Hello again.... this is already beyond me... I have checked it again, because the cables were fine, it still does not work, but now I have changed the motor to try another axis and the motor does the same thing (it is as if the driver ruined it) but the other time I ran the test nothing happened.... what can I do?

Well nothing... things remain the same and now there are 2 axles that do not work!! I have disassembled the motors, I have checked the encoder output with the oscilloscope and I think it is fine (the only thing that seems a little strange to me is that the AM26LS31C heats up a bit by consuming 100ma at 5v adding the consumption of the chip plus that of the encoder. If I don't send any signal with the mach3, the motors that don't work for me The ones that are broken? The machine has had very little use since I assembled it a long time ago (more or less in 2014....) but I have hardly used it (I used it manually) and now that I need to make some parts it doesn't work for me. .any suggestion idea....
