I generally would try to use as much travel as possible, I.E on my big CNC I had clocked the travel for full 1500mm and measured the variance and adjusted to that. The longer the travel you have the more precise you can get. After doing 1500mm calibration, i attached a caliper to the carriage and check that to 150mm, and it was dead on to the micron.

Oh here it is. c:

Another very informative video. I can't wait to see what this machine and 400 watt spindle can do. Hope you plan to make more videos show what it can do and how accurate it is now after your adjustments. Keep up the great work.

Thanks, will do! please pass my videos on to friends and help the channel grow

Very cool of what you did

A strange thing. How is it possible that the first time you changed from 160 to 150 and the travel was bigger ?? In fact at the end to reach the 200 mm travel you had to change to 161.00 the values In theory the right value in this case should be 161,6162 (160/198) * 200

I’m doubly flabbergasted! Firstly that a machine capable of sub tenth of a millimetre precision is miles out at default settings. Secondly that you’re eyeballing it! What does the digital vernier say? Surely the settings should be based on the maths of of the screw dimensions and stepper motors etc. Should mention I’ve got a 6050 ready to assemble and coincidentally same VFD/motor combination you set up a few months ago. Your videos have been a wonderful source of expertise. Many thanks. PS. Enjoy your very familiar accent, South West England?

Yes, Chepstow! When machining wood with a CNC 0.2mm is fine, and you can easily eyeball that, please pass my videos on to friends and help the channel grow.

Much appreciate the reply. Apologies as Chepstow’s Wales not England, been there many times🙂 Don’t want to open a can of worms or show any disrespect but if my new Genmistu 6050 can only cut consistently to 8 thou it’s going in the bin! That’s more than the peak of ya cap. My experience isn’t with CNC machines yet but where I’ve used stepper motors, gears, belts and modern software heaving heavy stuff around in all weathers and am sure with careful setup I’ll get 0.8 of a thou. I’d have to take issue with your ‘woodwork’ tolerance too, there’s plenty of everyday CNC users making guitars etc where 8 thou would be hopeless. All the very best Roger🙂

I should add I am talking about the precision with which the router/spindle is being positioned NOT the final dimensions of the material! Humidity will not affect the dimensions of metal and polymer components.

How or where do you get the software and also is that in the mach3 or is that a separate software if so how do you put them together to adjust this
