Hello everyone, I am new to this and I am looking to now get myself up onto the better quality cnc ladder. I currently use a A3 Laser system which is very powerful and not chinese! I am happy with it and I use Lightburn and grbl on that, I have also a small desktop mill ( chinese) that i have been using for a few months to learn how to understand the basics of gcode and how the 3d environment works, Its not brilliant but does what its needed although its not a grbl board it only uses drufel and mach 3, the latter I am finding quite complicated. However it shows the process and I understand that. The laser is belt and the mill is screw. I have noticed with the belts that it is prone to needing adjustment over time. At the moment I do all my design in Easel and export to Drufel as I have a educational license. I would firstly like to know please what the differences are please between a Openbuilds Lead and a C- Beam machine, am i right in thinking the Lead uses Acme screws and the C-Beam is on belts or is it to do with the type and shape of the profiles/wheels Would I also be able to use a Makita router RTO 700 C until I can afford a larger and more powerful spindle. Also am I thinking right that the Blackbox Controller does not control the speed of these type of mills, De Walt, Makita, and a n other's ? How do you allow for that when milling please as my current mill stops and starts the spindle and will control the speed, do you just start the spindle running? Finally would I still be able to use Easel? The machine I am thinking of going for is a 1050 or a 1075 with the emphasis on the X mill head on the 10 length, simply as thats the type of rig that is best suited to my workspace. I understand the resolution is much better on screws than it is on belts but this is a fairly small machine so would it make that much of a difference, I guess also torque would be a factor as well with a lot more in a screw machine. Also that would be slower. I want a good quality finished product from what i make, I dont want to be sanding down all the time. I realise than some finishing is needed but the less the better. I will be using wood 75%, plastics 20% and Aluminium 5 % , that would possibly include copper and brass but only machining out a support plate nothing more really than that. I want to be able to make make name plates out of wood and plastics, boxes from solid wood, large letters raised items on wood etc. I work in cinematography/production and would also be small making items for use on sets like slates and other things. I also want to make some small toys for my wifes work. she is in early years and special needs. I have no problems working and designing in Easel and I am fine with Vector files and so on from lightburn. I still need a lot more experience which is why I will be buying a turn key kit from a supplier who I have now found and who is also a good maker/designer on here. I have no problem putting together a supplied kit, I might have some issues with calibration but general use should not be a problem as I have built a lot of machines and use complicated large camera rigs etc. I just would like to know the main question above and whether I am looking at the right sort of cnc build for a turnkey option. I want to use more than build a machine if that makes sense. although I understand that building it does give you insight in how it works and what to expect in maintenance etc.. Many thanks to everyone , Neil .
