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?
