Im new, am a 3D designer. Need a New cnc machine and need advice and guidance

I must be misreading this, I thought that Jazz and me would see eye to eye about routing aluminium, I did go to Specsavers so it can't be that.

No Robin we don't agree at all. I'm referring to the machines suggested lower down but your still banging on about that old chest nut that Routers can't cut aluminium properly.! . .Which is frankly stupid because there are many of us on here that do it quite nicely thank you.!

Agreed on the concrete machine thou, correct Concrete and epoxy can make a very solid machine.!!

That's a relief. I was just doing the forms to renew my gun/explosive certificates, can't afford anything that might cast doubt on my sanity.

I resent that :P I ahve learnt allot from this bunch, also I reply quick when I want to learn quick..seems most post on this forum are responses 2 weeks apart...

They will be if you don't start reading and stop asking annoying questions you should have learnt. .

Wasnt refering to the people on this thread, You ad two others have been superb in terms of replying :P A compliment :P

Hello again, Right After going thourgh more of the build logs..Updated teh design of my gantry...people using 10mm 2D cut steel and wled it all together, Im using 6mm and have just reinforced it allot... Simply for cost. When it comes to driving the belts, I have done the drive system using the belts and Pulleys Jazz reccomended(your real name?) I did the basic calculation to get the mtor shaft to pulley distane and added a couple holes where i can add tensionsers if the tensions isnt quite right..

When it comes to the X axis, Its currently using two motors...but reading around Im seeing a fair few people having issues with losing steps (similar to z axis on 3D printers) how much of an issue is this? If so Ill redesign for a big belt using one Nema 34 motor driving both ballscrews (cant find it but saw a diagram you posted Jazz...)

Help?

Ok well don't worry about losing steps. Those who are losing steps have usually either overtuned the motors or have mechanical issues. If you use decent electronics and don't be greedy regards tuning then you won't have any issues. Regards electronics then get out your head any relationship to 3D printers and absolutley don't look to buy electrics intended for 3D printers they are far removed from each other.

Single motor and belts do give peace of mind about not racking and do allow faster feeds has they can be run closer to the motors limits with worrying about stalling. But like you will have seen me say before if you've read other posts if twin motors are setup correctly and run comfortably within the motors torque capabiltys then you don't have any problems for majority of work. If running very long 3D work(15hrs+) then I prefer twin belts as you know one motor can't run out of sync with other.!

Keep reading and you'll find my Name. .
