Hi Bob, Before going to the hassle and expense of setting up a fourth axis, try a couple of alternative piercing strategies: Wiggle or zigzag pierce. Keep the...

Its just about 6 weeks until the annual CNC workshop in Galesburg Illinois. I spoke to Roland the other day and he is now working on the seminar agenda. If you...
We have finished the first batch of Z columns and got the first one assembled and test yesterday. Ends up with 16" of Z travel and much greater rigidity. With...
Hi Ron, I gave a couple of talks last year and offer to give some this year. Main issue for me seems to be that everybody wants to go to all the talks, so...
Hi guys, I stumbled across a complete setup (transformer, powersupply, servodrive and 1.3kW brushless motor) from Baldor ASR. The problem is that I can't seem...
Thanks Les! Exactly what I was looking for - someone familiar with how it is really done as opposed to me guessing. The preheat is very efficient and I can get...
Hi all, I'm using a Gecko G320 on my mill , I'm putting a 10 Amp Fuse in the mid. of the wire between the motor and the driver, this fuse helps me not to load...
... I think this isn't a good way to do what you want to do. You may be setting yourself up for a blown driver if the fuse goes. Put the fuse between the...
Anybody have suggestions for sourcing inexpensive power caps for power supplies? I need something in the range of 25k - 30kUF, 75VDC. Thanks, Andrey Lipavsky ...
... Have you looked at the Power Conditioning module sold by www.pmdx.com Its not the cheapest way to get power capacitors, but its very handy and not a lot...
Can anyone give me the current e-mail address and/or phone number for Rick Chownyk - Want to talk to him about the upcoming CNC-Workshop June 16-21 - My old...
I have about a thousand electrolytic caps, 14000uF 35VDC. I know that's below your voltage requirement but you can gang them up with bypass resistors to get...
I usually buy from Digikey or Mouser online. You might check Allied online while you are at it. None of these are real cheap, and you might find some on e-bay,...
... Yes. Mouser has a line of "sanp-in" capacitors by CDE that are quite reasonable. I have a few here that are part # 5986-85-63V12000, manufacturer's P#...
You might check out this list of electronics surplus dealers: http://www.arrickrobotics.com/surplus.html Caps will dry out and older caps will need to be...
If you decide to use capacitors in series, keep in mind that the effective capacitance value is reduced for series capacitors. Two 140,000 uF in series is...
I am wondering if it would be worth my time and effort to go to the CNC Workshop in Galesburg. I have a Bridgeport Mill and a Lebond Lathe that I have run off...
Brad, There will be a lot of activity. The EMC guys will be there most likely working on some machines. The work sessions are worth the trip. Robert Colin...
... I think its a great place to meet and talk to other guys doing CNC projects. I missed last year, but the year before there were almost 200 guys there and...
At Galesburg there are training sessions on a number of subjects like wiring controls,understanding how to do things, run Mach and configure it to do do you ...
Just d-loading your video - nice stuff ! I appreciate teh specs on the mill / emc2 combo. What size rails do you have ? (Ie thk 25 mm - 15 mm dual block etc ?)...
... I'm driving the servo amplifiers (essentially simple H-bridges) with PWM from the m5i20 and reading the encoder counters with the m5i20. It's not the...
Is this an either/or? I've seen diagrams showing both, does it make a difference which to use, other than it depends on the e-stop button you might have on...

Monte. The typical Estop (EPO) button is a normally closed push button (switch) that needs to be twisted to release it. I use mine in my electrical enclosure...
On my CNC Taig mill, my mechanical e-stop button (which mechanically opens a NC switch until it is turned and reset) disconnects power to the Xylotex stepper...
