PRS Standard

[dan78]

Hi guys,
I just receive my SB Standard, and start to set him up ;o)

I would like to ask , how are you guys disconnecting the motors on PRS Standard control box. The cables came from the box pre-mounted for the motors, if you have to troubleshot the square of the table, obvious is a no go for moving the gantry with the motors hooked on the control box.

What are the steps what you are doing to disconnect the motors.

Cheers DAN

The motor cables disconnect from the motor side. It is not advised to disconnect them from the control box where they connect inside. When you wire it up, you'll run the spindle, spindle fan, proximity switches and Zzero plate TO the control box (and VFD) & You'll run the motor cables FROM the control box to the motors.

It certainly makes wiring more difficult than it should be, but it isn't too bad if you are neat and organized - which means you are adding to the reliability of your tool by making sure none of the wires get snagged etc. Be sure to keep the wiring neat and add zip ties to keep wires secured.

Thank you very much for your fast answer ;o)

I was not very clear with my question , but you nailed right ;o)

Basically if later a problem will require to unplug the motors ...we need to cut the protection foil to unplug the motors. Or to troubleshot any problem with the gantry with the motors down from the track.

Please let me know how you deal with a problem like that ;o)

...we need to cut the protection foil to unplug the motors.

Dan, I am assuming that you mean shrink tubing ? Then, yes...carefully cut it away, do what you need to do and re-shrink. If you wire things correctly and give yourself some extra slack where it is needed (like wrapping once around the Y motors to allow for pinion replacement & zip tie the wire to the motor) then there isn't much to really worry about. Worse case, you just unplug the motors.

Yes , you are right ;o) I was thinking to shrink tubing ;o)

Okay then , tomorrow I will connect the motors, and the control box, and give a run to hear how sounds ;o) maybe I can do even same dust ;o)

Just to double check , how are you felling the gantry when push with the motors engaged. Is moving relatively easy, not that easy for my wife ;o) , I can not fell any bumps is going pretty well all the way, but I just want to make sure is not to tight, I could read on other thread about problems if the motors are engaged to much.

Thanks again for you fast answers ;o)

Engage the motors as tightly as you can into the racks. Lift and rock the motor into mesh with the rack and tighten the screws down. 'Too tight' is for the older PRT models.

Try not to move the gantry or Y or Z around too much with the motors plugged into the box. The motors become generators and you can damage the motor drivers if you generate too much voltage by pushing by hand. If you MUST move it by hand, either drop the motors out of mesh with the racks or move very slowly.
