Some of you might remember me as the guy building the steel 750mmx750mm table. Unfortunately I ran into a problem when I mounted the Yaxis because the blocks were inaccurate due to my bench drill and tools I used, thus, the bearings tore into the stainless rails.
I decided to use the blocks, rails and bearings to build a smaller machine out of MDF (400x400 table) and hence it is now finished bar some fine tuning, Ive posted some pics and will post a movie when the tweaks are completed. I will use this machine to complete the steel machine as it is surprisingly accurate.
I have some queries and would apreciate any advice on the following..
I have the Rockcliff 4axis board and 270oz.in steppers and was wondering what is the maximum voltage I can put through the motor? the motor is 2.8A phase, would it be safe to put 2.5A through each motor? I have it set at 2.2V equivilent to 1.3A at present but could use the extra power..
I have ordered 6 limit switches and estop, I made switches for the MDF machine from my sons Lego, 2 rivets and a spring which are sometimes unreliable (but still work..) when the new switches arrive I will rewire and box the PCBs with a fan. My second question is as follows:
I was wondering which wire to use for the motors? we measure here in awg (no idea what it means my electronics is very basic) I would apreciate anybodies advice, meantime when the rewiring and boxing is finished Ill post a movie in action,
Thanks for that Rockcliff, I have another small question..For my board what are the step pulse direction settings for mach3? appreciate that,
The Manual and Mach3.xml setup file are located in the manual
hope that helps
Thanks again.. Im a little slow on the CNC lingo but what is PFD? The answer is probably obvious..
Hi if your controller is a V10 model it will have a setting for PFD (Percent Fast Decay)
it's not a critical adjustment, but it can help to fine tune, for mid band resonance (vibration, motor chatter) see
or look over the V10 manual http://www.rockcliffmachine.com/Rock...rDriverV10.zip
Thanks again, the board I have doesnt have PFD, it must be an earlier or later version, Ill set the voltage to 2.5VDC. at present there really isnt a problem with the setup but I cant get much more than 750mm travel per minute using M10 screws which is enough to make the blocks for my steel machine, I have ball screws for that machine which should improve the speed when completed..
