General Mach Discussion / Using "GOTO ZERO" switch, Z axe stay in low (-) position

« on: December 07, 2019, 01:04:26 AM »

Hi

My problem is - from recently, when i use "goto zero" command switch, my z-axe no more raise up to safe distance (+20mm) and then go to x0 y0 position, and then z0!
Instead of that z axe stay in curent (low) position and x and y go to 0.
- if z is in (minus) position, then movement crack my bit

How can I set this so before x and y go homing to 0, first raise z axe to safe heigh say (+20mm)?

thanks for help

General Mach Discussion / All home, precise backward .mm - problem

« on: March 12, 2019, 05:24:52 AM »

Hi, friends
I have a problem with homing.
Usually when I press "ALL HOME", it first go home z axis then X and Y.
When the x axis hits the switch at end of movement, then the ax gets backwards few .mm, and then slowly to hit the switch again (for better precision, I suppose).
My problem is ...sometimes when the axe going back - not going far enough and do not release activated homing switch, and machine stop with message (emergency stop active-endstop)!

- I use the same switch for homing and endstops
So where to control how many steps or .mm axe going back before going to precise hiting the switch?

lp, chris

Hi, I cheat my CNC (see video) 

https://youtu.be/3wBpa7--aBM

For now I'll use push switch with z axe! It's working ok for now

Is there a way to use direction pin on my z axis for controling on/off my laser?!

General Mach Discussion / Laser 15W setup with 4axis USB board

« on: February 21, 2019, 03:54:55 AM »

Hi, friends
Need help!
I use this board
 https://cnc1.lv/en/cnc-controllers/273-usb-mach3-100khz-breakout-board-4-axis.html
with my CNC 6040!!
I purchase this  laser
https://www.ebay.com/itm/15W-Laser-Head-Engraving-Module-w-TTL-450nm-Blu-ray-Wood-Marking-Cutting-Tool-o/183115085067?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649

How to easy connect laser to this board (Mach3) using only z settings or spindle settings to turn it on or off... (I do not want to make some big modification)?!
Is it possible to use TTL or PWM with this board?

For graving I use Vectric!

lp, from Croatia

Great work Tweakie! This pictures are made with diode laser and Mach3?
