Oops, double post

Thanks. I ended up pulling the loom apart and individually tracing wires. The machine is now up and running on LinuxCNC. It isn't finished yet but it is basically working. I'm still working on adding...

Does anyone have a copy of the wiring diagrams for a Hurco Hawk 30? I'm in the process of retrofitting one and I don't have the manual. Hurco in their infinite wisdom didn't number the wires so the...

To expand a little on Art's description, the sequence is as follows:
CAD Create the drawing of your part
CAM This works out how to cut your part and calculates the machine movements needed. It...

You are probably using a different layer. When you create your plasma operation, check you have the right layer selected.

There are a few possibilities here. Can you describe what you do once you have loaded the drawing into SheetCam. For instance what sort of cut operations do you set up?

If your spindle speed is very stable you may get away with this for rigid tapping. It also needs to stop and start quickly. You will have to experiment a bit and it is likely that you will break a...

This is fairly classic symptoms of a buggy display driver. I am afraid the only solution is to install the latest drivers for your display card and hope they have fixed the problem.

It is using Siemens drives but I am not sure what model. I can't get to the machine at the moment to check.

I'm not convinced. While homing the movement is smooth and stable. It is only once the index is found that it goes wild.

The machine was running fine then the Y axis ran away and tripped with a 'gross positioning error' halfway through a job. Now whenever you try to reference it runs away then faults immediately after...

I have an interesting problem on Beaver mill with a TNC145 control. If you try to reference the Z axis it runs to the home switch, reverses and finds the index as it should. Once it finds the index...

At the moment there isn't any way of doing that in SheetCam. I am negotiating with a supplier of nesting software to integrate their functions into SheetCam. Hopefully something will be available in...

The code is correct so the problem must be with the machine. Does this machine use stepper motors? Your fault description sounds exactly like lost steps on a stepper driven machine. If it is servo...

It depends rather on what you are doing. Simple engineering type work doesn't use much power. Engraving text and complex curves on the other hand can use quite a lot of memory and processing power.

I normally reverse the motors in ports and pins. Simply reverse the direction output. If it was hi active, set it low active or vice-versa.

If the text came out backwards in the X direction then the X axis is working the wrong way round. Reverse the X axis motor direction. Depending on the machine type the X jog buttons may now seem the...

First of all, is the drawing the correct size in SheetCam? Use the measure tool or simply use the mouse position display at the bottom of the screen.

In Mach, make sure the scaling is set to 1...

As you can tell, documentation is not my forte. I am trying to locate someone to do the docs.

The post processor issue occurs because there are so many different machines out there. The example...

You are using a post processor designed for a machine that has a manual Z. Go to Options->select post processor and pick the Mach2 post.

SheetCam will try to cut what you draw as closely as possible, within the physical limits of the machine and cutter. if you have a sharp inside corner you will end up with a radius equal to the...

Hi Mike,

First of all, you need to be careful with your drawings. Lines must join up exactly. You cannot have any gaps or overlaps. Remember the machine has to follow the outline smoothly. A gap...

You can't directly machine bitmap images such as GIF, JPG, BMP etc. You need to trace the image first. I would recommend tracing it by hand in Corel but you could try CorelTrace. CorelTrace will only...

Nesting relies on recognising patterns and how they can be made to interlock. Humans are very good at pattern recognition. Unfortunately computers aren't. Computers have to work by sets of rules and...

Sorry, no it doesn't. I would like to add this as an option in the future.

Yes, use the < and > keys. They will rotate the part 5 degrees at a time.

Ther are two places you can set it. For testing, use the 'set post processor variable' function in SheetCam (button with a big V on it). The variable name is 'switchoffset' (without the quotes)....

Currently it tries to minimize the rapid distance between parts. At the moment you cannot change the cut order. I am working on this.

In the mean time, one solution would be to nest the parts in...

Thanks. Are the G0 Z1 moves just to go to a safe height? If so, I'll change them to be compatible with metric as well as inch. I'll also do a few other minor tweaks and upload it for you to try.

No problem. Do you mind if I include it in the SheetCam installer?

Thanks,
Les
