Snap! Although mine was on the X axis. Took me ages to work out what the slight ticking noise was.

I replaced all of the couplings for ones such as listed here:
Flexible Couplings : Zapp...

Indeed he did. Mine is currently as effective as a boat anchor and one step away from becoming one.

Been a long time since I took my spindle out, but I seem to recall the sleeve being held up by fairly high spring pressure and you need to push it down to allow the C clip/washer to the removed.

Very nice. Good to see you moving forwards.

New control going to take much getting used to?

Not the same machine(SX3), but I did have a few problems with a similar thing happening when the coolant was switching on!

I traced it back to the relay board sometimes going bonkers as it...

That is one big honking vice! :D

Are you making your gibbs out of anything in particular?

Not entirely sure who in the UK stocks replacements for these machines and the one I did get from Hugh was out of his parts donor machine...

Hehe Ed, to answer your thought about the Z gibb moving, previously I spent a fair bit of time getting a replacement (as the first was so bad it was out of adjustment range before it did anything...

Sorry to hear of your problems. Makes you wonder if they take any notice of the complaints.

As far as I'm aware, Mach is totally open loop in axis and spindle control. This is why you can't do...

I'm going to take the table down to my friendly local precision engineers and put it on their measuring table etc. just to see if I'm totally losing my marbles or if there is an actual issue, whether...

Agreed Jeff, cranking down on the bolts could influence things. The torque wrench is set to 20NM/15ft lbs which for me equates to a moderate hand tight with an allen key. As four clamps are used,...

Thanks for the reply Neil.

The face mill is an Iscar 50MM eight insert body using APKT10 aluminium inserts. The depth of cut for these passes was 0.25 and 0.5MM on a block of 6082. This...

Been chasing my tail a bit recently trying to work out the cause for steps in material when face milling, as this is what first brought my attention to the issue.

Judging from the step it appeared...

170IPM for the rapids is pretty snappy, is that using the standard steppers?

I think if you want more speed or range selectable speeds, then you're going to have to go your own way with it. I've not seen Syil offer anything other than changing to the X4 motor and...

Have you tried running the spindle in manual mode to see if that narrows it down to CNC control?

I've not run the spindle under "computer control" for a very long time due to it's general poor...

Looks good Andrey. Very tempted!

Unfortunate situation when questions etc. don't get replied to. I got distracted whilst pushing a query and haven't as yet established whether its worthwhile pursuing Syil electronics or going down...

You'd certainly turn a nice shade of blue and eventually a fetching purple. As stated, this inconstant (if it ever got an initial response) communication has and will cost them future sales.

Sorry Chris, completely missed this for some reason. As is stands now if I try to use the spindle under CNC control it takes about 40 seconds to get to the final speed. This final speed is quite...

Thanks for the information Chris, I've been looking at ways to get the spindle of my Syil SX3 back under Mach control as the existing Syil control board is woeful in this respect.

This gives me...

Although this was my first attempt and the fact that it is for the Z axis, I could get away with not getting the bends perfect and it still works very well on my SX3.

I used 1MM 304 Stainless...

Given the area I wanted to allow for the mill I decided to base it around an enclosure area of 1200 x 1000MM. The mill is offset within that space to take into account the end mounted motors and...

Thanks for the information. I've been gathering bearings etc. to do the job and this will help a lot.

A quieter spindle and the possibility to get it under full CNC control - must be dreaming :D

Thought I'd update this as I've just measured them again.

Axis ---- Measured MM

X ------- 0.036
Y ------- 0.045 (not so great)
Z ------- 0.039

Short of running the X and Y very loose on...

It was just the bearings at the end by the stepper motor, ball screw left alone. It could possibly be a case of the lead screw to stepper motor coupler flexing a bit that adds a small amount of...

kenealym I've got similar 'twistability' in my ballnut and with the gibbs adjusted as they are now, I measure 0.03MM of backlash (just a smidge over in reality). Mine might be tighter than yours or...

Nicely done. Still doing the hand tightening here.

Are you only going to use the quick change tooling? My need to use other tool holders is leading me go down the impact wrench route for a...

I've made a couple out of fairly average (as in I have no idea what it is) steel and welded various end types on depending what I need at the top end. Not seeing any problems so far.

Xushuo you are correct that I haven't contacted you directly. I did discuss it with Hugh, but I've not pushed him since then.

If you have a kit price and shipping options to the UK already...
