hi all, assuming that it is possible to make the spindle turn at a constant speed, is there a way to specify this speed to the threading gcodes instead of...
It probably is possible Dan. But a one pulse per rev encoder is a very simple thing. I use a proximity probe and a little bit of steel held on with a hose...
Paul it is not the sensor but the system behind it. my electronics knowhow=zero and although i have seen several references to the very low cost of components...
Paul that sounds interesting. would you care to elaborate? i always thought that the parallel port takes 5v as a signal. will 12v not fry it? i do not use a...
OK, So you are using drives with built in optoisolators like Geko's? Opto isolating your IO is a good thing to do. But it gets surprisingly complex very...
Hi Dan, It might be a little messy, what with all that fruit! Seriously, it's probably just easier to make up a sensor. Need a schematic? Parts? Ideas? ...
Paul i think i understand it. clearly it is not like the magnetic switch i planned to use. could you give me a brand/part number? i will try to find one in...
Alan seriously, i wouldn't recognize a 555 if it hit me in the face unless it had the number on it in bold letters. even then i wouldn't know what to do with...
Hi Dan, I am proposing a little optical tach circuit. I use it as input for a PIC tach a built. I've attached a JPG; it will probably get stripped off for ...
could you use a magnetic pickup from a push bike computer? ,the type you attatch to the front forks and then screw a magnet to the spokes? cos there cheap! ...
Has anyone else noticed that 'home axis' done on the Jog screen and G28 in MDI mode is handled differently? In Jog, if I home all axes they travel one at a...

hi, I have just wired my spindle motor via an opto22 solid state relay. It swithces through pin 14 perfectly using M03/m05. But,a strange and dangerous thing...
... The BEST way is to turn on your machine after tcnc is ready. At startup some bioses put post codes on lpt port and check if some devices are connected...

Hi Ya'll uploaded a file called dan-cnc.zip which contains cutting profiles for a doll cradle, guitar pick and a program that allows you to cut in multiple...
Hey Dan, neat project. Just in time for Christmas. My daughter will love it. Though I think I'll use some nice cherry hardwood for the sides and bottom. Say,...
I forgot where I saw it, but I saw someone has a board, that is supposed to be hooked into a parallel port pin, and the computer generates a regular signal by...
Owen, If an axis is not backing off the switch, it sounds like something is not configured correctly. Which version are you using??? A plain G28 should move...
Hi Art, That's what I thought as well. I know the ol 3.1 did it that way. I believe I'm using ver4, but I can't check right now [I'm at work.] What sort of...
How come I can cut english threads perfectly and not metric thread. I use the program Odthread to generate the Gcodes. I import these on my cnc lathe and when...
Owen, you might like to try the "enhanced G28" version of V4.01 that is in the file section. This way, you can test one axis at a time under MDI. Simply type...
Howdy Owen: I don't do anything special, cut material oversize and clamp at the edges. I do this because my machine is very lite weight so I have to cut in...
