Super Kitty says "thank you".

Good luck with your collecting. If you have any technical problems with your CNC build, the guys on this forum are brilliant and only too willing to be of assistance.

All the best,

What sort of machine do you have Will ?.

Hi Vince,

Sorry to hear about the work slow down. Very nice sterling you are making there.

General Mach Discussion / Re: can you move the motors manually

It's completely unnecessary to move the table manually - Move the part to its new position, jog the table to where it needs to be, and re-set the DRO.  This is the more conventional way of handling your problem.

Brilliant solution here by Ray. Coincidentally that is the way I used to do it before I fitted the disable switches. It is only when you come to actually making stuff that is longer than the table size that you discover the most convenient way of doing it.

Luckily, in this world, there is always more than one way of doing everything.

Hi Henry,

Hood is the expert on this type of conversion, I am sure he will be able to help.

By way of explanation for what I use the axis disable for :-

I have had occasion to make wooden signs that are longer than my work table and so they have to be routed in stages. When the progress of the work reaches near to the end of the table, I pause Mach, disable the Y Axis, reposition the work and table manually (with the cutter in exactly the same position on the work), re-enable the Y Axis then restart Mach for the next phase. As Mach knows nothing about this repositioning (DROs remain the same), the work progresses as normal. For this to be successful the routing on each part of the job must be complete prior to the move and this sometimes means some GCode editing prior to starting the job. It is perhaps a bit long winded and does require positioning jigs but this method does enable work that is longer than the cutting area to be undertaken.

Hi Josh,

As RC has said - I have fitted toggle switches to the enable lines of all axes and this is great for manual repositioning.

Ben,

Do you need complete positional control of the two Z axis or is is just 'pen up / pen down' as you would have with a plotter ?.

Hi Ben,

Whilst Mach is capable of controlling 6 Axis the software to produce the necessary GCode for positioning and controlling your two arms would be extremely specialized. I have no knowledge of any such available software so I think you would have to write your own GCode for anything you intend to produce. Simple stuff is OK but you would have to be extremely serious to write GCode from scratch for complicated products.

Hi Himy,

After trying many possibilities it only happens when 'Machine Coordinates' are checked. So uncheck and problem solved perhaps ?.
