Well.....
I wired the driver for the A-axis into the BOB pins for the Z-axis, same result.
Looks like my eBay driver is the source of the issue.
Got any suggestions for a good replacement, 42v...
Hi all
Issue:

Nope, just cutting raw.
I have also been running a "traditional" 4 flute mill cutter at 5000RPM on HDPE at 1000mm per minute. The result is real chips, no spirals of cooked plastic, clean finish and...

I am adding an Arduino board to by 8020 T-slot router as an environmental monitoring system.

Hi
Pd011 is also zero, I have played with various settings for both 11 & 73 as per previous posters on this subject suggesting they both had to be right.
I did find something strange, my...
Yep, thought I was right.
Trouble is, IT DOESN'T WORK !!!:boxing:
I can get between 16000rpm and 24000rpm but no lower than 16.
I spent all day on this yesterday, cannot work it out.
The pot...
Thanks for the super quick response.
I have the manual here, from what I can work out it is Pd70 and Pd72 and Pd73 that I need to play with, correct ?
70 = 0
72 = 400
73 = 0
right now.

Still...
Wow, nearly two months since I updated this.
Finally got some workshop time and now I have this:

I cannot tell NPN or PNP, all I know is it works exactly as I wanted it to.
Yes the LED is lit when the slot it open but goes out when I block it.
Cheers
Got it working
I think the issue is that the schematic for the ZD1901 as posted on Jaycar's site is wrong compared to the physical package; the collector and emitter are reversed on the output...
Thanks Al, I will drop by the local parts store and grab some trannies tonight.
My opto must be the operate on dark type, as measured with the multimeter I get 0v at normal state and 4.99v against a...
That would be very generous of you, thanks
Hi
By "wrong" do you mean Collector and Emitter reversed ? I thought so too based on the other CNC Zone post but when i looked at figNoggle Designs: Photodarlington Optical Interrupter Switch...
Thanks Al
The opto is the ZD1901 from Jaycar here on Oz, http://www.jaycar.com.au/products_uploaded/ZD1901.pdf
Wiring is like the pic attached.
Could I trouble you to expand on the wiring...
Yeah I can but if the power fails on that circuit or some other fault occurs, Mach3 wont see it.
Howdy all
The router build is coming along well, cold weather means I am indoors doing fiddly things instead of the shed so the opto home switches are on the agenda.
I am using the circuit as...

Attached herewith for you edification and enjoyment.
Sketchup files of some common parts I have done to create my build, thought they might be useful to someone.
Hi
The swarf issue is one I am aware of which is why I am looking at this setup for homing only; i.e. when the environment is clean. I looked at my original post and the title and now see my...
Would you care to expand on that ?
Cable is cable is cable, if the cores are big enough to handle the voltage and current I could wire it up using anything from 20AWG hookup to 2AWG monster cable....

did not get a response so I am widening the net. Apologies...
Saturday afternoon update time.
I was stripping some old gear at work for the dumpster and salvaged a 19" rack mount case. Perfect to house the electronics for this project.
