I've nothing set in the tool information window, the status says "soft warning on X min"

That's good news, they are a LOT cheaper than the thread mills I saw for over £150 (which gave me a nose bleed) I've got some of those from my lathe, I suppose I'd better pull my finger out and fit the VFD and spindle encoder.

Thanks for the info

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

Jim

I've been using Eric's plug in for a few weeks now. I must say I'm very impressed. It works very well and must have saved me hours and hours of work already

Thanks for clearing this up for me. Could I use something like this for a 4th axis with a servo drive?

Thanks Hood, I'll have a look at that

General Mach Discussion / Squaring up a job

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

Jim

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

Jim
