Boxford v190 cnc

[depronman]

BernieNUFC - a massive thankyou for the PC's that arrived todays. I have cleared them out with an airline and installed LCNC on the better specced one.
Not conencted to the mill yet, but running the jitter test it looks very good at well under 20,000

Thanks again
Paul

great news thank you, glad to have helped

Likewise Bernie !
Thanks from me . I havent got it up and running yet . Tells me Boot mgr is missing but I presume I will get some advice from here on how to deal with that, and I am guessing that a Linux install will have different requirements anyway !

Ya the hdd will have been wiped so the pc doesn’t see a boot manager which is normally part of the windows install
When you load linuxcnc it will then provide the linux boot manager and all will work perfectly

I see no reason why the post processor would be different between the 190 260 & 300 vmc
They are all just larger versions of the smallest 190 machine
The addition of a tool changer would add complexity but not really to the post processor

I’ve never used the boxford software but suspect it is written for its target audience which is education and training but I see no reason why it will not be ok for the capabilities of what is a fairly small mill
A 4th axis (rotary table) may be the deal breaker but equally may be a capability in the boxford software

Let us know how it goes
Get yourself some polystyrene sheet to practice on it’s much cheaper that breaking cutters

Cheers and best of luck with it

I think i might try to learn the intricacies of the machine with its own software have the manuals etc, i then hope that i can go Linux or mach3 and increase the capabilities i.e. 4th axis.
With that said if i can get to grips easier than expected maybe there will be a path to sell this on and get a bigger one that i can use at work as opposed for just my hobby, who knows ?
Polystyrene, nice one :-)
Cheers Paul

The foam insulation material in about 50mm thick is ideal

Best advice I heard recently was Kingspan or similar - a better structure than polystyrene (okay, the dust will kill you - but that's better than the polystyrene balls electrostatically sticking to the inside of your workshop) and builders (around here at least) tend to sell on excess on the local Facebook sales sites.

EDIT: Actually, think I just repeated exactly what depronman had said (apologies - I saw "foam" but read "polystyrene"...and the Kingspan should be attributed to ngwagwa)

Thanks doddy, i have just pulled some out of my garage loft that was hanging around, will give it a try.
I have used a cnc router without too much problem as it was with vectric so most of the work was done and made some nice carvings and acrylic jobs but metal is a bit more difficult with fusion and this pp as i have no idea at that depth :-)
thank you

Update on the HP small format PC that Bernie kindlt sent me - it may help other
I have spent all evening trying to get linux to see two parallel ports

There is one onboard from the motherboard and I installed another PCI parport in the only avialable slot (White slote at the very right hand side of the m/b)
Firstly the PCI card MUST be a slim height one as the HP is not very tall, not a problem as the ones I bought from ebay a few weeks ago are slim enough but I will need to modify the mounting bracket or back plate of the card as its meant for a full height case

having fitted the card and rebooted fire up terminal and type in lspci -v
this reported the PCI cardat address 1100 and 1108
from past experience I know that you use the latter of the two addresses with 0x before it in linuxcnc hal file, so this means the pci card is seen at 0x1108
so far so good

now in termin type dmesg | grep parport
This reported -
parport0: 0x378 irq7
lp0: using parport0

So happy days linux can see both parallel ports

so, run a dummy stepconfig wizard, set to 2 parallel ports, crash any data in the rest of it
Start Linux and it crashes, stating it cannot find a parallel port
no great problem, i've had this issue before as Linuxcnc tries to define the parallel ports as 0 and 1, but this sometimes works and sometimes doesn't work, but you can amend this in the HAL file by using the actual address instead of 0 and 1

loadrt hal_parport cfg="0x0378 out 0x1108 in" this should do it

try to start linuxcnc, still crashes with same error

I spent 3 hours going round in circles, removing the pci parport, changed it for another one, tried another pci card in the slot on the M/B with a spare sound card, all worked perfectly
What the hell is going on !!!!!

Into the BIOS and set the parport on the M/B to bidirectional - same problem, set it to all possible setting, still the same problem, until I set it to disabled
You read this right DISABLED
saved BIOS setting and rebooted linux
run the above two terminal commands and was surprised that the PCI card AND the M/B port was still seen (even though the BIOS was told to disable the onboard parport)
Started Linuxcnc and no errors this time, into HALSHOW, pins, parports, 0, show all input pins (10, 11, 12, 13, 15) then port 1 show all input pins (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 15)
connect a parallel cable to each port, using a jumper wire in pin 25 touch pin numbers above and HALSHOW lit up each pin
So, all is working correctly

But would you 'adam and eve it', it only works if the onboard parallel port is DISABLED in the BIOS

I thought it was worth posting my findings to save others getting frustrated / giving up

On another note - I cannot get linux mint to install from a pen drive, it will never start from the pen drive even after F9 for the boot menu and selecting USB Boot
The pen works on other PC's / laptops perfectly so its not a pen drive issue
Any help on this would be appreciated.

I installed Linuxcnc from a DVD, but only had the mint version on a pen drive. I can't find my stock of blank DVD disk to burn the mint iso to a DVD to try, will have a look tomorrow when her in doors is at work (sure she as put them somewhere safe)

Cheers,
Paul
