General Mach Discussion / Re: Is Mach Stopping My Stepper Driver?

« on: December 13, 2010, 05:30:00 AM »

I have had a look over the german one, but i dont actualy think its the correct board anyway?

My only next step it to look for an electrical person, to test it all, as im not overly confident to what im actualy looking for!

There is no reason for MACH3 to do this is there?

No me either!

I feel so lonely with this now, i can see this costing me ££££

I just dont understand how it can go from perfect to junk in a 30min drive!

Well - Since its dead, i might aswell post some pictures of my machine in its prime!

Now this is where i think somethings not right with Mach...

If I plug Say for example:

The 'Z' ribbon from the interface to the right hand board - I get no movement
The 'Y' ribbon from the interface to the right Middle board - I get no movement

The 'Z' ribbon from the interface to the middle hand board - It works
The 'Y' ribbon from the interface to the right hand board - It works

It would seem that each output from the interface is spacific to the driver (i don't know how that would even work, as its only a signal & all boards are the same

Also the interface board as a small (looks Like & monitor plug) for dignostics i think:

Its just all strage very strage...

My other option is just to bin it, or make a CNC lathe just using 2 axis!

Im gutted that i cant find any information at all

Hood, Thanks You For Helping Me!

You helped Me Back in 2008, when these same boards were in 'Sleep' Mode' (Enabled Port 1 Pin 17)



I have attached a quick sketch to show what i have found:

The 'Interface Card' Looks to be working fine, 4 LEDs indicate C/Z/Y/X Are getting information/have power

Each Board is Recieving 36v From The PSU

Each Board has green LED On (This Tells Me its getting signal I Think)



On the Stepper Board that is working, i get something like this: (But dont quote me - its in the ball park range)

5v - 3v - 5v - 3v - 5v - 0vGND

i have checked this at the pins

On The Non-Working Board

0v across all of the pins on the actual board - Nothing at all...



I have taken the board out to check / look for dry joins, broken parts etc, nothing! Still looks like new!

The boards are:

Langenfeld 2.1a stepper driver rev 1.2 - (No documentation ATALL on the internet)

I just dont understand where to fault find?



Mach3 Configuration:

All I did was unplug the Unit (Powered Off) & Un plugged the Stepper drivers

No Changes made to Mach3

The i found out it was not working, I deleted my Cosha.xml configuration file from Mach3 folder - then dropped a back up .xml configuartion back in...still the same problem


Now thats as far as i can go, i just don't know what else to do!

Any help would be great!

Hello Everyone...

Im Begging Anyone to help me with this, i have tried everything I Can Think Of.....


Ok, i have been using Mach3 for 2 years on my little desk top CNC Machine.

I took out my machine to take to a workshop to get a few bits sorted, i got there any for some reason my X movement has gone totaly...

I have opened my CNC controller, all 3 stepper boards have power, all LEDS are showing that there is a correct signal from My desktop to the controller, and 2 of the 3 stepboards are working perfectly...

So what changed in the 30 min drive to the workshop?

I have spend 2 days SOLID trying to workthis out and i just can't im totaly upset about this as i dont think there is anything i can do...


Can Mach3 totaly stop a signal getting through to my cnc controller?

I cant find any documentation on my stepper boards, all i know is there 'Langenfeld 2.1a stepper board rev 1.2'

I have checked and re checked everything, but i can find out whats stopping this motor from moving...



I/O Port On PC = 0x379 - Same as Mach3

Like i said the other 2 motors are working fully under Mach3 control, now im at a loss...

Can someone throw some ideas that i might have missed out on?

Thanks in advance...

Cosha

well my table area that i can reach is 960mm x 790mm so its medium desktop. not bad for a first attempt!! once you get your head round the basics its really nice to see your creation come alive!!

thanks for all your help hood!

just a quick update!

sorted out the mpg and all is ok

circles actualy come out round and not oval egg shaped!

and just had a mess around with text inside mach one of the wizzards! ACE i could actualy even read the 1mm text so im very happy!

just waiting now for my end mills and the only tool i have is a round nose engraver and its quite big so i wasent getting very nice cuts, still tomorrow i can mess about with feed rates!

my feed rate is only 300mm at the min its slow enough to hit that big ol red button if things go (.)(.)'s up, but nippy enough to entertain me!

i think now i really do have the cnc bug and i blame everyone here! and mach for making life so easy!

yeah there not overly cook an egg on hot, i can hold onto them for a while just like holding onto a hot water bottle, they do cool failry quickly when the controller is turned off mayby 15-20 mins

so my 133.6666666 was close, i did try to work out it on my own but can get quite confusing when you read something then read another thing about the same problem and its totaly different, i guess thats where every motor and set up can be different!

is the heat caused but alot of resistance inside the motor?
