Im also considering using 3 x 3 .125 or .25 wall square tubing for the main body and cutting table rather than 2 x 2 .125 wall that the plans call for.
I watched a youtube video of a torchmate 1 plasma setup and the undriven end of the gantry seemed to be lagging behind the driven side. Is this a common problem with the tm 1 setup? I just want to try and stay a step ahead and adress all of the issues that i see before I start building and have to build it twice. Sorry about the laimens terms im new to the cnc world.
