A axis

Got the A axis wired to the driver and Masso. It will only turn in one direction. A- and A+ produce the same rotational direction.

Thank You

After checking the wiring and restarting a few times it only goes in one direction. Depending on how it is wired either the A+ or A- not both. Do not have A axis in the homing sequence.

Edit ---- Ignore this post and check out the next one.

We know your X axis works OK, so swap the motor connection with the A axis at the drivers.

Then operate X+ & X- to see if the problem is the MASSO or the motor wiring.

The reason for only one direction rotation is in the A axis settings you have minimum travel set to zero, try -360. This will allow the axis to rotate both CW & CCW from the zero position.

I spotted it in this topic Setting Up Masso with Sherline Mill the last post by trevorb58, he included an image of his A axis settings.

Yes, I caught that negative value thing when I was swapping around wires to see if motor would turn the other way. Did not help. I swapped the X and A axis wires at the drivers and A turns in both directions. Not the X axis only one direction.

Thank You

When you first turn on Masso, only one A axis button works. After you use the Y- button both A axis buttons work but turn it in the same direction. Disconnected the Y and B axis and the same thing happens. Y- will make the A axis turn. Did not notice before because I had the A axis turning so slow. Speed it up and now you can see it.

Thank You

This is pointing to the MASSO as being the problem. From point on you need to get @masso-support involved.

Sorry I can't help anymore.

SN: 5A-3310 5 axis v 3.41.8a

B axis slaved to Y axis. Wired parrallel so I did not have to install another limit switch. DM542T drivers for each motor. 24 volt power supply just for Masso. Two 36 volt power supplies for the drivers. Two DM542T for each power supply. Wired the A axis driver to the Y axis power supply since it will not be used in rotary operations. Could give it it's own power supply but did not think necessary. Using proximity switches for limit and homing.

Thank You

Roie

When it is close to homing position, but it usually it is not. I Jog it over close then home it.

Thank You

Roie,

I think what @masso-support was asking, can you successfully home the machine before you try to rotate the A axis.

I noticed that you don't have Request home on startup or Request home on E stop press ticked in the Homing setup. Step 6 in the MASSO homing documentation request that you do that. That shows on the F3 screenshot that you posted on your WiFi question. As the E stop button should be dark without the words Press button showing.

Regards,

Arie.

Yes I can home the X,Y,Z axis not a problem. Either before or after rotating the A axis. As far as the "Request home" goes I never paid it any mind. Had too many other problems. If it will fix the A axis I will do it now.

Thank You

I don't know if it will fix the A axis but it will get the machine into known state.

@rroie just read the entire post again and not sure what's the problem, can you please make a video and show us all the steps from powering the machine to A axis issue as we might pick up something.
