Rotary attachment help

Post by Malcolm Lewis » Wed Jan 04, 2017 7:36 pm

Purchased a rotary attachment to try my hand at a bit of engraving on yeti cups. My machine offers a rotary attachment connection on the front, side wall. I have watched videos where the "Y" axis cable is disconnected and the rotary attachment cable is put in its place but this isn't an option on my machine. I assume that Y axis is substituted for the rotary fixture through the software interface "Enable Rotate Engrave".

Before connecting the rotary cable, should the machine be powered off? I am guessing that the machine recognizes the attachment when it is powered up and this creates the interface between the two units.

Any help would be appreciated.

If your y-axis cable isn't to be disconnected, yet you have the connection inside the work area, you will most certainly want to power down the machine when making the connection. It is possible another forum user has cooked/bricked/fried his controller or other component by performing a cable change with the power on.

I'm unfamiliar with your specific machine, but it behooves you to do your best to track down the controller end of the rotary cable in order to better identify the proper operation. For example, if you trace the cable and discover it's attached to an otherwise unused port on the controller, you would not have to disconnect the y-axis, making it all the more likely that the Enable Rotate Engrave feature works for you.

Someone better qualified than I, perhaps an owner of a similar machine would be a better choice for advice specific to this instance.

This thread I started might help you out. I have a port inside my work area but still have to swap out the connection at the controller too.

Thanks for the help guys. Doug, we apparently have the exact machine. Does this mean that it isn't neccessary to use the "Enable Rotate" function in RDWorks? I will give it a try tomorrow

I am a rotary newbie too (see your private messages) but what I have read so far indicates you still have to enable User tab > Rotating > Enable rotating. Hopefully someone with real experience will chime in and advise.

Keith's write up in the forum manual is very helpful- I used it a few weeks ago. Your rotary will rotate in place of the Y axis without any changes as the stepper driver does not know which motor it is connected to- enabling in the user tab has more to do with changing the speed of rotation in order to make the controller understand how much to rotate for the engraving operation.

I started experimenting with rotary before the manual, so I haven't read that part, but I have never enabled rotary in software. I'll have to give it a read now out of curiosity.

sounds the same as my machine, i'm just finding my way with the chuck rotary too (took me ages to figure out why i had no movement till i traced a broken wire on the rotary itself.....) Any hoo, yes power down the machine, plug the rotart into the round plug inside the laser bed and then unplug the Y controller block in the laser case side panel and plug in the spare block that should be in there, this spare block should trace up to the plug where you plugged your rotary into (there will be a couple of wires looped into the main Y axis plug though.) make sure the laser head is out of the way of the rotary for now and power up the laser, the rotary should do a load of fast and slow spinning then stop, pressing up and down on the laser control panel should now spin the chuck. I've heard some people need to move the laser head up to the top right possition to trigger a senson but i've not had to do that.
Then its off to the software....... thats what I'm currently figuring out to get the work to engrave properly without elongating etc.

One of the things I did was make a relay control to switch between the normal Y-Axis stepper and 3-roller rotary device. Now, I just plug in the rotary device and throw a toggle switch that drives the relay, then off I go.

Of course, you should still power down the machine, plug in the rotary device and throw the toggle the switch, then power up the machine to prevent 'spiking' the stepper controller.

Hans, that looks like a really convenient setup.
