90 Deg V Carving

Hi all,

It was really very nice to go out to the shed today with laptop under my arm and just plug it into the CNC, power everything up, load the G Code, reference zero and hit go and just have the results appear before you with no fuss, no lost steps, no noisy steppers.

This is how it's supposed to be isn't it. I had gone to the trouble off borrowing a couple of different stepper drivers to try and solve the noisy steppers and missed steps at slow speed when stepping any finer steps that half stepping but today I produced this with the half stepping settings and I think I've decided to stay with that.
The other drivers I had borrowed were Gecko G201's and I had little info on setting them up and some info I read said you needed a special setup in Mach3 to run them. As I only had two I was unsure as to whether I should run a mismatched system so I chose not to at this stage but while reading about them it mentioned about the exact problem I'm having and that there is a trim pot on the Gecko driver to adjust the driver just for this issue.
Well only one of the borrowed boards has the trim pot, the other has fixed resistors so anyway as mentioned I chose to stay with half stepping as it seems to do a pretty good job for me and well the proof is in the pudding as they say so my two most recent jobs the toothed sprocket and the V Carving today have gone without a hitch so don't fix it if it's not broken.

The test run is for the lid for the jewelery box as shown before so now to find a nice piece of wood to make it out of.
My young brother is into wood turning and has a few mates that do fine woodwork they should be able to point me in the right direction.
