Wanted: BT35 1/2" side lock toolholder

All my BT35's are metric but have been given half a dozen brand new 1/2" TIN coated end mills so need a holder to suit. Only collect chucks I have are ER16, not big enough, or DA180 which is really designed only for drilling.

Thanks ...Sweep

Re: COMPRESSOR FOR TRIAC ATC

Hi Rich, The ATC has very little demand as you are only filling, if I remember correctly, three small cylinders and only the two that drives the carousel in and out and up and down are double acting; the spindle release is air operated but spring return. I don't even have my compressor running as th...

Re: New Triac Retrofit

Hi David, I have just ignored the fault boost and energise lines. I suppose a nice touch would be to get an input to Mach3 for the Fault signal but i'm not sure how, or why, you could utilise the Boost. My drives are continually energised as long as there is power (set with the jumper on the drive b...

Re: Balluff Proximity switch sale - Free P&P

You mention "old stock."
What might you have lying around for a Triac ATC (BT35) ?
Will call round and collect if you any Triac stuff that is heading towards the skip!

Re: Help with Triac VMC converting to Mach

Hi Dave,

The flat springs are about 12mm wide and have little 'barrels' attached to their ends. These barrels are 10mm diameter and 20mm long.
They may actually be one long spring with a barrel at either end if you see what I mean.

thanks ...Sweep

Re: ATC Toolchanger logic

Thanks for the uploaded info. Some of it must already on the site hidden in other documents as I seem to have quite a few of the pages.

ATC Toolchanger logic

Hi All, I have a late 80's Triac with 6 station BT35 ATC controlled by NEE SMCU; actually the serial number of the ATC is 001! As part of my very long modification to Mach3 I want to still keep the ATC. After a lot of time with the oscilloscope I captured and recorded the code that is sent from the ...

Re: Help with Triac VMC converting to Mach

Dale,

What toolholder type is your ATC for ...BT30, BT35?
A couple of my flat springs on the carousel have snapped off which means I only have 4 stations available.
Mine's a BT35

Re: Triac ball screw pitch

As far as the capacitor modded circuit is concerned, is this what you mean? Also, considering the old age and delicate nature of the PKS Digiplan SD2 units, are we pretty safe installing these capacitors? Since posting last someone pointed out the error in my maths as I have lost around 20 pulses to...

Re: Triac ball screw pitch

Thanks for your thoughts Angel-tech.
As i'm a bit of an electronics novice can you just eloaborate where exactly to introduce the capacitors. If you could print off the drawing, sketch on your mods then re-scan it that would be fantastic.

Re: Triac ball screw pitch

Hi Steve and thanks for your input. The stepper drives are still the original PKS Digiplan SD2 items driving the original motors. They are interfaced to Mach3 by a simple transistor array (see attachment) though I will be changing this to an opto-isolated creation if I can sort out this distance los...

Re: Triac ball screw pitch

No luck. I have dropped the acceration right down, increased the step and direction pulse width from 5us to 20us, besides trying other settings in-between, I've tried changing from active high to active low on the step, but still i'm coming up short everytime by exactly the same amount. I even incre...

Re: Triac ball screw pitch

I'll do some more measurements tonight and also count the number of teeth on the timing pulleys. I had taken the ratio as 2.5:1 by turning the z axis pulley as that is easiest to get to. mabe an extra tooth on there may have caused my error. I agree with your assumption that 201.8 steps/mm would nev...

Triac ball screw pitch

I thought the pitch of the ballscrews on my 1988 Triac were 5mm but after doing some sample measurements using Mach3 it seems that this might not be the case. With my Imperial DTI on the X axis and programming a move of G0 x12.7 (i.e. 1/2") I get a discrepancy of around 0.003", that is I measure 0.4...

Digiplan SD2 needed

Probably due to old age (the sd2, not me!) my X axis drive has decided to give up the ghost. As such I am in desperate need of a spare.
If you are on with a Mach3/Gecko upgrade, or just have spares on stock please get in touch.

Thanks ...Sweep
