The lathe was running on Linux through the PP. I then got another pc (laptop) with mach3 on it and added the SS.
Because of the problems, I then put a blank Hdd in the linux PC and put windows on...

confirmed..

just got the other pc going, installed mach. took the machturn file of the other pc. typed M4 s1000 in the MDI line. and the chuck started going CCW.

so all is well using the...

tried some things today..

just for ease I told mach3 the coolant (m8) is output 2 pin 1 the same as the CCW trigger. but before I did this I told it was output 1. so when you turn on the coolant...

no meter check, but if you lift the lid of the lathe (turns on safety switch) you can hear the c11 relays click and the spindle doesn't come on. the pin 16 relay clicks. pin1 relay doesn't.

can do...

Hi,

just got my self a Boxford 125tcl. all up and running with Linux cnc. problem is that I don't know Linux, so as my other cnc stuff is Mach i though i would convert it over.

I got the pin's...

hi all,

could do with a bit of help here.

been looking for a 6 axis bob (U.K based) kind of like a C11 board, but not a C11...... if that makes sense.

found this one PLC4x-G2 breakout...

right then.........

its all up and running..... ish. both axis are running well no with no stalling and that with the new pc.

i have had to frig the spindle problem for the time being buy...

sorry fastest1 missed this one.

when i phoned to order them i said i needed 2 and maybe 2 more at a later date, he then asked if i was running the machines at the same time? i said just one at a...

it was set up to use step and dir.

the bob is a c11

it's sod's law that the only thing that did work well on the lathe is now not working with the SS :-(

there both USB.

thx i'll give that a go.

yes its an SS setting im changing.


what does Linearity.dat do?

this may be tempting fate, but by jo i think we've cracked it :cheers:

two SS's turned up today. just fitted one to the new pc. the difference is like night and day.

as you all know, with the...

quote "Some PCs just won't work above a crawl."

is this still the case if using an SS? or am i clutching at straws.

as this is not my lathe i cant just go and buy another pc as a maybe. he's...

thats it i give in!!!! it's beaten me.

the only thing i haven't tried yet is a graphics card and that cos the only one i have want fit ether pc.

it seems the problem is getting worse. the...

both pc's have integrated graphics.

i might have a card laying around covered in dust. i'll dig it out and give a go.

this is the old pc. its a 2.8 with 500mb ram.

ill give that lot a go.

when i said the motors are in parallel, i meant the weirs from each motor. not 2 steppers running off of on driver.

think i get what you mean with the newer pc. i did my mill about 7 odd years ago and the pc i begged for that one was already a few years old. and a part from a few hiccups in the beginning its been...

i was right.... he didn't like it :-(

ger21...

could you explain this 100khz step rate? or would this be the kernel speed?

ca't remember what it's was called, but the was a list of things...

thx, something to read at work :-)

SCzEngrgGroup

thx for the explanation. in a VERY round about way, sort of how i thought it did. but my version was a lot less technical :-)

so if that the case, whats the point of them?

as i thought the problems is sending pulses through the PP with no buffer. i.e strait in strait out kind of thing. so if the pc does have a fit for a...

think your all right :-)

it may just be the pc. when i did my mill i got a pc plunged it all together and it worked...... in the end. when a mate of mine did his, he tried 3 different pc's before...

had a chance to have a look at the bios. couldn't find anything in there about (C1E or EIST), but i did find something that urns off one of the cores.this i did and still no joy :-(

did notice one...

thx ger21,


i'll have to give that a go latter........ off to work :-(

thx for the replies guys.....

the old pc was a 2.8 with 500mb ram.

new pc is a 3.6 duel core with 3.5gig ram.

i have up loaded some pics and a vid of what its doing.


fist pic is the...

did the driver test on the new pc.... showed little spikes. i know the old pc did as well.

ill take a screen shot of both and post them.

hi all,

seem to have a problem with a Boxford 240 cnc retro.

ill try and keep this short.......

got this lathe all kited out to run with mach3, still had the original steppers on it. every...

so i now have a motor, power supply and a controller. my problem now, is i have no idea what to do with them.

i know you can fit a 10k pot to the board to very the speed of the motor, but i have...

for got to mention this will probable be a long build.........


been collecting some bits. found a pair of ground rails on ebay. 900mm long, 20mm wide and 4 carriages. brand new never been used....

thx for the link:)

the lathe he's building is roughly the size I'm after. only difference being the head stock on my lathe will be bolted to the same plate the rails are on.


like the way he...
