Hi Martin,

Static is generated when the cutter pulls the material (like a Wimshurst machine). The charged particles travel up the tube and at some point have enough voltage to generate a spark. I...

Martin I have seen this before somewhere! I think the answer is to tape an un-insulated wire spiralled around the tube along its entire length and then earth that.

Hiya,

I hadn't seen this reply before I posted mine, fingers crossed for you and good luck.

To add to my reply, I did wonder if it was a problem with the controller but I wasn't sure if you had...

No guarantees, but I saw something very similar when I first set up my 3D printer. What's the max current setting on your drives? Yes, decode those DIP switches! Could be that if these are set too...

[emoji106] good start to the year! Well done Martin!

Depends on ballscrew pitch and Volts your running steppers at. But given it's relatively light weight construction ie not heavy gantry and using External motion controller then some thing like below....

The Amps should match or be close to the Motors rating as possible. Good drives will let you set exactly to match motors but If no exact match then set to next lowest. You'll just have lower than...

Q2 - wiring. Those two circuit diagrams are effectively the same. Not sure why you would want to do B. Diagram A shows a short wire connecting two terminals on the BOB; in B you need two longer wires...

Martin A mute point but I might have used Brown and Blue for the 230V cables and red and black for the DC stuff. Its very easy to get mixed up later. Or now it has been done use a different...

How's it coming on Martin? Any updates?

Very easy to tell the picture shows you all you need to know. Just realise the picture is showing you contacts without the Coil energised. They just Flip when powered up.

Take the First Contact 9...

Martin The ones I linked to will be fine and yes the drawing is OK If you are going to just use one input.

But do the Estop circuit as you have been advised by Jazz earlier

If you run your target bolt head axially on to the sensor, one day you will jog onto it and crush the coil in the head. Put your sensor at right angles to the motion of the axis, so the bolt passes...

They will sense Aluminium but you have to get very very close and they are erratic so NO is the answer. Sense to a bolt head or Metal plate etc.



Clive answerd that he does what I do.

Well here's one £1.40 http://www.ebay.co.uk/itm/LJ12A3-4-Z-BX-Inductive-Proximity-Sensor-Switch-NPN-DC-6V-36V-NEW-/191736625652?hash=item2ca464b9f4:g:UFkAAOSwvt1WQ~S R

Look harder and you'll buy...

If your going to have Inaccurate home switches then there's no point having them at all really.! . . The whole point is accurecy and repeatabilty and you'll lose this thru a relay.

If the KK01 can...

Ok I've done you a quick Diagram but If your not going to listen your just wasting peoples time and I'm time short as it is.! So either take heed or don't waste my time asking questions your going to...

Don't get too wound up about the total consumption via the mains plug. The VFD is rated at 2.2KW. That means that it is capable of delivering 2.2KW, not that it actually takes that power all the time...

Ok but you will need a few more bits.! . . . Nothing expensive but important to have. Momentery Reset Button and Some Relays. Plus if you want a best noise immunity then a 24V PSU.
I also suggest...

Ok Ill explain. So your Incoming Chasis power has you call it is providing power to the drives which all pull a certain amount of current. Lets say 4A each then you have other items possibly pulling...

Martin

Have you thought about how you will operated the VFD controls, in my opinion I would not mount the VFD inside the control box.
All the grounding sheaths should go to one central point ie...

I recommend checking with a multimeter what the resistance it between each of the pins, as who knows if the companies making these spindles are consistent. You should get a couple of ohms between the...

Sorry to say this but that machine won't be able to cut anywhere near those speeds & feeds.!! It's just not strong enough. If it did manage to do them it wouldn't handle them for very long before...

This is how I set up my 2.2KW VFD. Connect both ends of the speed pot across ACM and 10V on the top row of connectors and connect the wiper of the pot to V1 on the bottom row of connectors.
I think...
