Tangent Corner / The Silly season has started.

« on: June 19, 2011, 09:13:50 AM »

The silly season has started at work where the foreign visitors and groups get show around.
I hate being put on exhibit so a few of these dotted around should, perhaps, give the management the message. 

This is Traffolite engraving laminate with a Clarendon 4 line typeface using a 90 degree engraving point and a depth of 0.3mm.

I can only guess but VFD's can be a major source of noise - check with the instructions that it is connected correctly and that it has a good earth connection and also that your incoming mains supply provides a good earth connection.

I would be inclined to look for electrical noise from your spindle or spindle switching system. Any electrical noise on an axis step pin can cause unwanted movement of that axis.
Can you please give us more details of your spindle and controller type ? (photo's perhaps).

Far too modest Hood.

You help us all a lot more than you perhaps think.

Could it be that you are operating in exact stop mode ? if so try changing it to constant velocity (Config  :General Config ; Motion Mode).
Check your GCode to see if it contains a G61 if so replace it with G64 and test the results to see if there is any improvement.

Tony,

I think you will find that G31 works with 'A' as well.

Jim,

I think the easiest solution is as both Tony and Terry have suggested in their posts above. You can get reliable delays from a few uS upwards by using a non-existent axis in this way.
VB macro's will also have their own minimum delays so it depends on the smallest amount of delay you really need as to which is best.
