Aawills,

I suggest that you check 'Config / Ports & Pins' that you actually do have kernel speed set to 25000. There is seldom any need to go higher than this.

* I hope the ball screw has the same pitch as the lead-screw you are replacing, because the back-gearing is designed to work with the lead screw to get all the thread combination's. As this is very unlikely to be the case, you may have an interesting time getting the thread cutting going. Good luck.

Not sure why id keep any of that junk, the computer will cut the threads not the bucket of gears and crappy lead screw (only has about 3mm of backlash - I must have got a good one)

I must admit that I don't know much about lathes but I will be extremely interested to see just how this pans out.

Obal,

Download unzip and transfer the DLL to your mach Plugins folder.

Hi John,

Sorry for not replying but I really have no idea what is going wrong. I have not seen this problem before, the write wizard always runs fine for me.

Sorry.

flemgunner,

I have just run your params through the write wizard and GCode loads and runs just fine (had to increase feedrate though).
I have no idea just what you may be doing incorrectly to cause the problem.

Sorry.

Art,

Thank you for the time you have spent with the plugin, it is much appreciated.

I have been set the challenge of how small a checker board (8 x 8 squares) can be engraved and still resolved under a microscope - at the moment I am down to 0.5mm but hoping to get smaller than this using the plugin.

btw. I think Bdocks code is the current download http://www.machsupport.com/plugins.php

Henry,

Not sure I fully understand your question. A single transistor circuit would be all that is necessary to drive a solenoid why a PLC ?

Andrea,

Excellent job on the solenoid, very neat and compact. The method of operation, one pole of a stepper motor driver, is brilliant too (I would never have thought of doing that).

You can see the same problem of mine in the third picture (Top right) when you use the DLL with the laser.
Surely no one noticed because the Y stepover of the fault is less than what I use (0.2 mm)

I don't know if it helps you but you are not quite right in your assumption here. The shading (top right of my image) is caused by the reduction in laser power output during the acceleration and deceleration phase of the axis at the start and end of each line. A similar effect is shown in the image below.

Keep up the excellent work, for some reason I missed this thread but I will be following with great interest now.

Thank you for the update Andrea.
I have not seen or heard about the latest DLL, I am still using various 'workarounds' with the old version.
I have downloaded and will try the new one.

I will look at you solenoid next.
