Tangent Corner / Electrical Regulations Safety Checks.

« on: July 16, 2010, 07:27:11 AM »

Under our new safety regulations the electrical inspection checks have to be done every 6 months now.
I had to do this one myself because our useless electrician refused to issue a safety certificate because he said it was a death trap.

Brian,

I have never found the need (yet) for more than 3 Axis at any one time and I am sure that with a bit of planning that is all that may be required. So It may not be a bad thing to stick with MC and save yourself a lot of, perhaps unnecessary, dosh.

Hi Brian,

I think it's all related to the price you are willing to pay for the software.

'MeshCam' uses an indexed 4th axis toolpath and is very well priced whereas 'DeskProto' will allow the 4th axis rotation machining you mention but at a higher price.
(As with MC the DP software is available for limited trial so you can see if it will do the job you require before you buy).

Moving up in price 'Visual Mill' will also allow 4 axis simultaneous operation.

There are lots more out there but these are just the ones I have tried and used.

ASC,

Editing your GCode should not be a problem - even using the 'replace' function in 'windows notepad' you can add something like "C-5" after every instance of the code which turns off the dispenser in a matter of just seconds.

Spitter,

Changing the G91 (incremental) to G90 (Absolute) in the first line will help a lot.

Tulsaturbo,

As Hood has said 'steps are steps' and these are calculated from the relevant axis motor steps, lead screw pitch, micro step setting and any gearing used - they have no changing relationship with the computer that is used.

General Mach Discussion / Re: Drifting X-axis, making step ladders one side whereas other side is smooth- SOS

« on: July 13, 2010, 11:03:58 AM »

Hi Khalid,

It is possible that the arcing has caused a problem with the driver for your X Axis. (Possibility - an arc produces so much energy that this could easily be translated into false step pulses by a driver).
Have you now replaced the damaged connector pin / socket and tried it again ?.
