Mach3 Breakout board help please.

I'm in over my head.

I'm retrofitting my cnc with a Mach3 break out board and I need a little help since Ive never done anything like this before.

This is the breakout board I'm using: www.gbeshop.com/InfoBase/SAVEBASE/PKG/00...erfaces_fw_r2_c1.jpg

1: The proximity switches on my machine are these: www.ia.omron.com/product/item/tlq_2001e/ The blue and brown wires are connected in parallel along all the sensors so I assume that one of them is common. The black runs back to the board for each one so have connected them to the X/Y/Z Axis Limit Switch spots on the left of the board respectively. I assume that one of the others (blue I think) would be ground. The brown would be voltage input? I have connected it directly to 5v. Does this sound correct?

2: The Emergency switch at the moment just cuts all power to the machine, should I just leave it like that or wire it into the break out board? Cutting the power seems safer, are there any advantages to having it controlled by the software?

3: My VFD is run by an Atlee Inverter. This seems to be the exact same one : (pdf) www.atl88.com/uploadfile/20100719/20100719153822563.pdf

Do I still need to wire something into the 0-10Vspindle speed Output Connect? There where only two wires running into the inverter, one into pin 7 - FWD and one into COM. I have just wired those two into the Spindle ON/OFF Control interface at the top right of the break out board. Is this correct?

4: The stepper controllers had the white plugs on them so I have just plugged them into the "5 Axis Common Anode Interface ...." slots above the bottom row of pins, do I need to run any additional wiring to the controllers?

I have downloaded and pre installed from the Linuxcnc live install dvd. I'm a little unsure about the pin layout of the board I'm using, can someone help me with a pin layout?

Also I have no idea about the stepper settings for my drivers (www.aliexpress.com/store/product/2-phase...02844_382651457.html), my idea was to leave them on the default settings and then play with them until I get them right. Could I damage anything by doing this?


Sorry if some of the questions seem stupid. Any help would be appreciated.

This forum deals with linuxcnc, however happy to help
help.
Your omoron proximity switches connect between +5V and your breakout board input.
some proximity sensors are 2 wire and some are 3 , if they are marked + & - then they go to the 5v and gnd and the third wire is the switched input to the breakout board

Brown = +5v
Blue = 0v
Black = input to bob

Thanks! I am using (trying to) LinuxCNC. I was told I could use the mach3 breakout board with LinuxCNC? I sure hope so!

yes you can ,

attached is a schematic of how you should have the steppers wired
i need to look for info for the vfd , but if you need to control the speed via the interface then you may probably need a interface pwm to 10v

you may probably need an extra relay for forward and reverse

i'd leave the estop circuit as it is , but we can interface that into linuxcnc later as an input signal
