CS-Lab / Index Homing
« on: December 15, 2018, 06:31:19 PM »
Hi Guys,

I'm using CSMIO IP/A on my old bridgeport milling machine for a few years now. All has been ok, but index homing has just stopped working. I've reloaded a previous config and get same issue. So I think its a hardware / sensor issue.

The machine references the z axis fine, then starts the y axis, moves the the homing switch, and reverses direction, usually then it starts slow then moves quicker, but it doesn't ever speed up, and doesn't find the index.

any ideas what to check next? If I manually turn the servo the DRO on the mach3 DRO display changes , so I guess the encoder is working?

General Mach Discussion / Motor tuning Bocsh servo drives
« on: June 24, 2014, 10:06:52 AM »
I've got bosch servo dives fitted to my bridgeport interact. I'm getting a lot of chatter on my x axis, and often this trips out the breaker inside the machine. I guess this is down to motor tuning?? Does anyone know how I can use the document attached with Mach3, or is there any easier way to tune the motor?

thanks

Jim

I have a few programs which are all for the same job, and use the same tool, I'd like to combine these programs into one.

I noticed that the G43 values are not the same, is this going to be a problem?? I don't understand what G43 does. Any help would be great.

Thanks

G-Code, CAD, and CAM discussions / Gcode MDI move to machine coords
« on: April 16, 2014, 11:22:02 AM »
Guys,

I have a quick G code question for you, Can you move the machine to the machine coordinates and not the working coordintes with an MDI??

I'd like to make my machine go to x0,y0,z0 what command would I need to use?

Thanks

Tangent Corner / Is this possible on a 3 axis machine

would it be possible on a 3 axis machine? how would I make the lip on the top of the pipe?

General Mach Discussion / Ref all axis, and soft limits
« on: February 25, 2014, 08:43:28 AM »
Warning, Blonde questions coming!
Is there a way to enable soft limits on a machine which you have not referenced. Surely with persistent DRO’s enabled, as long as mach3 was shut down correctly, there has been no manual moving of machine then it should be ok??

How acculturate is if the referencing of all axis? If I were to make a jig to bolt to my table to hold a part, and I re referenced my axis,  how close in mm would you expect the jig to be to last time it was referenced?

Thanks

Jim

General Mach Discussion / holes .2mm undersized, backlash???
« on: February 19, 2014, 07:40:44 AM »
I did a test job on the weekend and found that the holes were .2mm undersized, could this be backlash?? whats the best way to measure for backlash??

Thanks

Tangent Corner / How would you clamp this?
« on: February 07, 2014, 12:15:41 PM »
I want to make this part on my milling machine, (photo attached) when I have machined the first side and cut it from the plate I will need to turn it over to mill the recess on the other side, and also the radius. How would you hold a job like this while machining the second op?

General Mach Discussion / Mach3 quick review
« on: February 06, 2014, 05:52:24 AM »
 ;D Just thought I’d write a post for anyone who is thinking of using mach3, either on a new machine build or retro fitting it to an old machine. I converted my Bridgeport interact mill with very little knowledge to mach3. The mach3 software is very obvious to use, and the backup support from this forum is the icing on the cake. Keep up the good work!!

General Mach Discussion / Recomneded plug in / macro for Auto tool Zero
« on: January 24, 2014, 10:48:25 AM »
I'm looking to auto set my tool heights.

Which plugin or macro do you guys use to auto zero your tool lengths, or should I say which one is best documented for a newbie to understand? ;)

Thanks

Jim
