,,The main reason for using a boring head is when the finished surface needs to be a precise cylindrical surface eg for a bearing or an engine...

Well, if you are using a boring head to turn the outside diameter of a part, you'd need to use a left hand boring bar. If you are boring out an...

Thanks. I believe a right-handed chisel goes from the inside out, so towards the opening. So with a bore head, you have to go from the outside in,...

It looks as if there's a small rotary switch on the side of each driver that allows you to set the peak motor current. Perhaps you could try a lower...

The boring head is threaded onto the arbor with a normal right hand thread, so it can only be used with a normal clockwise spindle direction (when...

Yes that's the way it is at the minute. I'm running dual motors on the y there running off one power unit and x and z on the other

That's what may be happening. Do you have one for x/y and the other for z?

I have 2 10a 36v power units maybe I should have 3 one to drive each motor. Would there be a spike when they first engage if 2 was running off the...

Poer supply doesn't have enough current capability?

I installed 2 new drivers and motors on my gantry they are cl57t and 4.2a closed loop motors with built in encoder. When I move my y and x at the...

Yes, I use it. Great controller.

What @Muzzer said, I have a Boxford VMC260 and is has homing switches but no limit switches. When you startup you home the 3 axis, if configured...

Now £1400 for both

After sorting the EMI issues I did a bit more development work then it was time to start on the electrical control panel . . .

Many thanks for the suggestion but I have now built the tool mentioned above into my F360 workflow and it handles both the G0/G1 rapids issue as well...

Hi Neale, I have a free online tool that does exactly what you are asking for. Open your .NC file, set the Z clearance height and press "Convert to...

Ah, that sounds pretty confidence inspiring. Those BRF brushed DC drives look very nice although a bit of a minority sport these days. Haven't seen...

Hi Muzzer, and thanks for your reply. I should clarify that UltraNC is not a company, it is a brand owned by my business Firestick Pty Ltd. Some...

Looks nice, certainly when compared to ncviewer - which was developed by an intern almost a decade ago. The likes of Centroid and Linuxcnc have...

Hi RobertE Interested in the machine and would like to make an offer for it Couple of issues from my side I would like to see it in action before...

Sold!

Sold!

It appears that my Star-mills are not as appealing as I thought they might be. Chat GPT has a lot to answer for. :( It is a difficult time to sell...

FYI, "NEMA" simply means imperial (inch) dimensions in tenths of an inch, so a NEMA 17 motor has a 1.7" square face. Beyond that, it could be a...
