General Mach Discussion / Re: Newbie with TB6560 1st time testing problems

Hi lads this thread is better than watching NCIS, I'm way out of my depth so watching with intent. Just one point, I looked through your threads and nowhere does it mentioned you set the port and pins settings to Port 1 ( at the end of the port and pin settings). I forgot to do this and spent hours trying to get my machines steppers to work. Will shut up now and continue watching. Keep trying Gary you will get there. Jim

Got to smile, the thought of you dog eating your cable. Before I retired I used to teach blind kids CNC machining at a local college. Their guide dogs looked on and I'm sure they understood CNC. SO Have you asked your Labrador for ideas!! Joking apart I'm like you ain't got a clue about electronics, but can confirm that the computer, and lead to your BOB are standard equipment, just checking its a desktop computer not a laptop, as Mach doesn't work with most laptops. There are lots of video's on youtube showing how to set up c your system, indeed one bloke does a drawing of the set up you need. Have a look. Best of luck. Jim

Hi Saw this on you tube http://www.youtube.com/watch?v=H7m7YkIXrvo
I know its for a 3  axis board but it doesn't help if the instructions that came with it were wrong. Good Luck. Jim

Hi AJ had any luck with your CNC motors? Jim

Hi AJ its Jim again, have you seen this thread about fitting Taig motors http://groups.yahoo.com/group/taigtools/message/30549 Might be the motors are no lined up or your jib strips are to tight or loose. Do you get the same problems with the motors disconnected from the machine. You can see I'm back to mechanical things.

I'm not sure I had a problem and looked at the Mach tutorial videos that said  a pulse under 5 is good and 25000 in another box said my computer is working well, but there was a spike of 10 caused by an electrical fault near to my BOB. I fixed that and all was OK. I assume the kit you bought was all wired up (the phases in the stepper motors were wire correctly) AJ I don't want to suggest to much as I'm at the limit of my knowledge. I'm a mechanical engineer who uses my CNC to make model steam trains, as I said electronics is invisible to me and dread the day my Denford packs up. Did you notice when you pushed the slider up in the motor tuning page the scale went through the roof that would cause motor failure. AJ I will watch your post with interest and chip in if I can help. Good luck mate you will solve it. Jim

HI  AJ I not an electronics man so I'm not the right man to talk to Hoods your man he will helped you out. The only other thing is when I first tuned my motors I pushed the slider on the side of the motor graph to high and bought in a new screen that took the motors to high, the noise for the motor was horrendous i thought I had burnt them out. Hope you get it sorted, its bound to be something simple and doubt its your computer. I take it you have done the driver test in the mach folder to see if you have any spikes in your output and your pulse rate is good in the diagnostics page. Jim

Might be stating the obvious but you have done the motor tuning in the config menu.

Read the bit on Absolute and Incremental codes in the G code tab on the main Mach page, it looks as if you have misunderstood their application. I think Mach always defaults to absolute unless you tell it different in the first line of your program. Looking at your explanation your machine is in absolute but you a thinking and programming in incremental. if the top of you component is Z zero and you are in absolute what you program in is what your machine will move down. Incremental moves a distance from your last programmed position. Best policy is to always use Z zero as the top of you componet, when your learning CNC it makes life easier, and saves a lot of broken tooling.
Incremental programming can be a nightmare when you first start programming.

Come across this, not much but might be useful.
