The akz250 has 16 inputs and 8 outputs. I know nothing about how to set up the out from the powermax to the in of the akz250. and visa versa. I would need an out from the bob to start arc...would...

I just picked up a used Powermax45 that I would like to use in a diy cnc tube/pipe cutter. I have a akz250 bob, what would I need to interface between the bob and the powermax cpc port? Pins 3 and 4...

I just used a battery until I upgraded to an ESS smooth stepper controller.

This scares me, for the last week I've been chasing down this bug of why the auto tool zero was not working with the help of all of you. Going through all these iterations but ultimately changing...

I went through and checked continuity:
0 continuity between chassis grnd and C25 grnd pin
0 continuity between chassis grnd and C25 +5v pin
20.5M resistance between chassis grnd and...

It measures between .005v and .000v but it's not steady, fluctuates between those numbers, more on the .000 side so essentially 0v

I had a suggestion from someone on the Mach support forum to add another 2.2k resistor in series to up the voltage to 4v to the touch plate. I did and it made no difference. What I am thinking now...

I never heard back from Arturo so I went ahead and set it up with the 2.2k resistor and it worked fine...problem solved, right? Not quite. After some fiddling around with settings I got the routine...

I'm waiting for confirmation that this is OK from Arturo before I implement this, I'd hate to fry a new controller before I got to use it!

I didn't put this in the 1st post but that's actually how I had it wired. What I've done is run an input wire from the touch plate to port1, pin15, bridged the 5vdc pin (between pins 12-13) and pin15...

Thanks for the reply. So if I run 5v to a touch plate and pin 15 to the probe/tool/spindle, shorting the 2 will not damage the c25 or the ess? Like I said I'm no electronics expert, I know next to...

When in the data monitoring utility there is no response on pin 15 (in the data monitoring utility) when I short the lead from pin 15 to board GND. The homing sensors are working as expected, pins...

I've searched for this info but have found next to nothing. The documentation of the CNC4PC c25 board says the way to wire up a probe for auto zero is to run an input wire to the bob on pins 10-13,...

Hi,
I'm a total newb to cnc. I just bought a Jcut 90150b router and it came with all the motor step setting in metric but I'm still in the stone age and work in English/inch. The z axis is set to...

I just got a JCut 90150B machine and I'm setting it up. I have a question on how to wire a Z Axis auto zero plate to a Mach3 AKZ250 USB Motion Card using the internal 5v power supply. The manual only...

Ahhh so Jcut provided the external motion controller, you didn't add it afterwards. I'm inclined to add an external motion controller instead of a new/old computer. A new computer is probably $100+...

I'm purchasing the same machine and want to upgrade to the ethernet motion controller as well. What did you use for your motion controller? Did you need an additional breakout box to accommodate it?

Did your 60100 come from Jcut set up for Mach3 or or NCstudio?

I just ordered a Jinan JCut 90150b, Wood Router JCUT-90150B, View wood router, JCUT Product Details from Jinan JCUT CNC Equipment Co., Ltd. on Alibaba.com with the Mach3 controller. After doing some...

You used rails that you bought from Online Metals? Are the rails from Fine Line Machined in any way other than holes for bolting the rails to the router table frame? The question I really want an...

I went to your site to look at this machine/plans but didn't see it listed anywhere...does it exist?

mostly foam and possibly some lite wood cutting

I've been searching through this forum for info and design ideas...maybe my search skills aren't up to snuff...but I haven't been able to find many builds with a 12"+ z-axis. Can anybody point me to...

Any input or info about the dimensional stability of plaster? Does it shrink when it cures? If so is there a predictable rate of shrinkage? What would that be?
Thanks

One more question. I've modeled a mold to cast a foam plug in that will be produced on an abs 3d printer. What if I were to make the mold out of plaster? That is print a mold for the mold to expand...

That sounds fine to me. How hot does the wax have to be to melt? Would it be too hot to pour into an abs mold? I'm trying to build an automobile intake manifold. I've already compensated for the...

Thanks for pointing that out. I was going down that road.
Is there any other pourable expandable foam that one could use other than polyurethane foam? I'm making molds for the positive plug on a 3d...

I spotted this which led me to research which led me here. Any how check this out: http://www.grabercars.com/content/view/67/2/
It's a 3mx3mx2m router table, or at least the beginning of one. He's...
