Gerald,

Should have posted this on the first of the month 

Wrong GCode file perhaps ?

You are quite right Hood, it doesn't necessarily have to be a NOR though as any inverting logic gate would do. In effect it would turn the logic of a normally closed contact into a normally open contact. (quicker to snip off the pull up resistor but it depends on personal courage  )

I think I will wait for you to kit it.

The Replikit laser cut kit for the Snipe sells for £39.95 plus p&p.

Jeff,

In Canada, is your neutral (white) at the same voltage potential as the earth wire  ?

Get it all bolted down then lets see some pics of the stuff you make, please.

How do ya fancy building one of these ? I have dug out some rough dxfs for it.

One of what ?  (no picture file attached)

General Mach Discussion / Re: Parallel Port woes - need advice

« on: April 13, 2011, 03:47:20 AM »

The only suggestion I can make is that you check your port address in device manager and that it is correctly entered in Mach. (in my case the address is 0378)

G-Code, CAD, and CAM discussions / Re: Enroute 4.2 to Mach 3

Hi Rob,

I have no experience of Enroute but in the past, when trying different software, I have always found the Fanuc post processor to work OK with Mach.

Hope this helps.

Dave,

Just the top box.
Interesting to see if the problem is noise related or if this makes any difference.

Hi John,

I think you have just discovered the reason your proximity switches were disconnected in the first place.  

The C10 pull up / pull down unfortunately applies to all input pins and adding a resistor will not solve the problem.
As I see it you could either.........
1) Do a bit of sugery on the BoB to remove the pull up resistor which is associated with the pin you use for the estop or possibly.........
2) Swap the estop switch from one with normally closed contacts to one with normally open contacts and reconfigure your active hi / low within Mach (incidentally I use normally open contacts on my estop and limits).

Given the choice I think I would go for the surgery but then electronics is my thing.
