Share Your GCode / Cutting circle

« on: January 20, 2014, 08:46:01 AM »

Hi Guys,
I'm using solidcam to generate my gcode. I've noticed that my circles and arc's are not very smooth. As a simple test I create a circle and generated gcode to go around the perimeter.
Does this code look ok to you, can you see why my part looks like it's been cut from lots of straight lines rather than one smooth radius??

General Mach Discussion / Can't move z axis z- direction

« on: January 18, 2014, 09:48:35 AM »

My machine worked perfectly a few days ago, but now I'm unable to move the z axis in negative direction, I've tried turning off safe limits, is there anything in the software which could be stopping an axis move in a direction?

General Mach Discussion / GCode problem

« on: January 15, 2014, 03:14:35 PM »

Can anyone see where I am going wrong with this Gcode generated with Solidcam. It should simply milling two circles of just over 100mm each with a 6mm cutter, but when I try to load the Gcode I get a warning about soft limits. I can jog past the area where the material is so I'm not sure what the issue is. Can you see what I've done wrong??

Tangent Corner / Thread Milling cutters

« on: January 15, 2014, 10:00:38 AM »

Some really blonde questions coming. I'm thinking of having a go at cutting threads on my mach3 converted Bridgeport interact. Is it possible to use a normal threading (hand type) tap or do I have to use a thread mill? Assuming I can use a normal tap, can I use a std m10x 1.5mm tap to create an thread of m20x1.5mm?

Thanks

General Mach Discussion / Squaring up a job

« on: January 08, 2014, 12:38:34 PM »

This was something I thought about while in the shower this morning.
Sometimes I find it quite hard to set a part up square on the bed before machining. Is there any option to do this:
Place a part on the bed, where it's not square on the X axis.
Use a probe or similar to calculate how off the part was over a measured distance.
From these measurements, calculate the angle of the part. (for example 45deg)
Enter this angle into Mach3, so if the gcode asked to move x +20 it would also move y +20  to calculate for the angle.
I know the calculated distance would not be 20 but you get the idea (hopefully) Did that make any sense?

hope so,

Cheers

General Mach Discussion / Mixing Stepper motors with servo's

« on: January 08, 2014, 12:30:46 PM »

Hu Guys,
I'm not sure if this is possible (I think not), but I thought I would check first. I want to add a 4th axis to my machine, I'm currently using a CSMIO IP-A controlling 3 analogue servo drives. Could I add a stepper motor controller (parallel Port base) just to control the 4th axis???

Thanks

CS-Lab / Probing with IP-A

Tangent Corner / Cheap but sturdy 4th axis

« on: November 14, 2013, 08:22:12 AM »

I've been looking for a 4th axis for my Bridgeport interact for a while.  There are the  cheap Chinese ones on ebay, but nothing very substantial. Does anyone know where I can find a sturdy 4th axis, I have my own servo’s I can use with it.

Failing this, has anyone got any drawings of a 4th axis so I can try and make one.

Thanks

General Mach Discussion / Probing plugins

« on: November 06, 2013, 12:02:26 PM »

Hi there, I've read quite a a few post abut probing, but none of the post of very recent, are there any probing plugins which work with the latest version of mach3? Intersted in touch probing or video probing. I have some 2.5D parts which I would like the replicate.

Thanks

Jim
