Having spent 3 days playing I have more idea now, it's windows 64bit that doesn't support parallel port cards properly (No TTL) which means no windows 64bit system works with parallel port breakout boards if I had a usb breakout board 64 bit works fine. I got linuxcnc installed but couldn't get it to work with the pci parallel port card and then last night discovered that's because the cheap assby Desertboy - CNC Routers, Mills, and Hybrid RepRapping
Spindle works, was struggling to get a suitable pc to control the machine so came home but found a motherboard with parallel port and my windows vista 32 bit CD between them should be able to get something talking Will need to get a better controller soonish.by Desertboy - CNC Routers, Mills, and Hybrid RepRapping

I'm using mini tower PC for my controller and running a molex extension through the back of the PC to my fans (And breakout board which needs both 5v and 12v.) but you can buy 24v PC style fans cheap I bought mine for under £5.by Desertboy - CNC Routers, Mills, and Hybrid RepRapping
Slowly getting there's not enough CY cable for the spindle now ordered another 5m's, had to order another pc £100 as well to control this machine. The orignal PC I had set aside for linuxcnc has no parallel port so rather than much about I bought a 2nd hand Core I7 3.4ghz with 4gig of ram so I can run Fusion 360 on it for Cam and it has a parallel port My main PC is 6 miles (10km) from the routby Desertboy - CNC Routers, Mills, and Hybrid RepRapping
Started to wire it up and immediately hit issues, £25 later with rapidonline Missing some connectors off the AM882's, 2 I bought from China are missing both 6 pin connectors & the 2 pin, of the one's from HK is missing the 2pin but the 2 pin is not needed for my application. Also not enough CY cable bought as much again lol.by Desertboy - CNC Routers, Mills, and Hybrid RepRapping
Good to hear, keep us updated on your first cutsby Desertboy - CNC Routers, Mills, and Hybrid RepRapping
There's 2 reasons to do the gantry like I did 1. I was going to use 1.2m SBR25 rail which is heavy so I decided this should be the bottom axis and use Hiwin clone (1.5m) for the gantry since then I got Hiwin's all round so this is no longer a good reason but I already cut the frame. 2. I didn't realise this until I mounted it on the table but having the gantry the long way gives you much betterby Desertboy - CNC Routers, Mills, and Hybrid RepRapping

QuoteVDX ... you can grind the M3x8 to any length Grind it to 10mm for me then please! Ha ha ha sorry couldn't resist, I had to cut bolts down I found the best way is to put a nut on the bolt then cut it and remove the nut and it cleans the thread up to be usable.by Desertboy - CNC Routers, Mills, and Hybrid RepRapping
Stepper Drivers arrived That's a 24v power supply in the picture was going to power the machine originally but not going to cut it anymore lol so I'll upgrade the ramps board to take 24v so I can run my printer nema's and heated bed at their full potential. Spindle is on! I like this angle makes her look massive (She's already pretty big lol took 3 of us to lift her, 1.5m*1.1m)by Desertboy - CNC Routers, Mills, and Hybrid RepRapping
Bolt length was frustrating in my build lol as I had so many different lengths and different types from M4 through to M8's there's well over 160 bolts in my build and 7 different lengths. I ended up ordering twice, first time the bolts as I worked them out in cad and then 2nd time 2 sets of bolts I got the lengths wrong lol. Are you're linear rail bolts M4's?by Desertboy - CNC Routers, Mills, and Hybrid RepRapping
Always the little things that get us but at least you've solved it now. Bet you can't wait to get her cutting now, is it a Shapeoko 3 you have?by Desertboy - CNC Routers, Mills, and Hybrid RepRapping
2 rails per axis, minimum. Steel is not flat so you will to need to epoxy resin to level where the rails go. Aluminium T slot extrusion is also not flat but it's flat enough for your style router (Or mine for that matter). Read this for gantry design ideas, what you drew wasn't a gantry lol but I assume you just wanted to illustrate the point. If you only have 4 rails (I assume you were thinkby Desertboy - CNC Routers, Mills, and Hybrid RepRapping
25v per output core, I was told once it goes through the rectifier it will end up around 68v's. (2 cores in series).by Desertboy - CNC Routers, Mills, and Hybrid RepRapping
Just got to work out where the grey and purple one goes and we can wire it up hopefully tomorrow we can start think about testing the output voltage. I'm assuming they are the other primary coil so should be wired in series I believe but will double check this lol. There are 2 primary coils at 115v. Right think I worked it out with help from another forum On the primary side Blue/Brownby Desertboy - CNC Routers, Mills, and Hybrid RepRapping
You're spindle mount is like this one isn't it? Because my spindle slides super easy inside the mount and only when I tighten the bolts does it become rock solid. If it is I would complain I know it's been a while since you bought but if you got it from ebay from Chinese like I did you'll be surprised sometimes how helpful they can be I've had a few items replaced no hassles no fee when I'veby Desertboy - CNC Routers, Mills, and Hybrid RepRapping
Quoteo_lampe I guess you can use : M83 ;relative moves G92 X0 ; set X axis to zero G1 X1000 F1500 ; move 1000mm relative from there (-1000 to reverse direction ) Not had a chance to play with her again but nice one 2 of my AM882's came and the other 2 will be next week so I doubt she'll ever cut with the arduino (Kind of sad about that, one day might wire the AM882's to the arduino justby Desertboy - CNC Routers, Mills, and Hybrid RepRapping
She moves very slowly lol using ramps board doing an X axis home (Repeatedly). I guess this is the Gcode I want to move it manually and up the speed? "G0 X12 ; move to 12mm on the X axis G0 F1500 ; set the feedrate to 1500mm/minute" Is there a way to make it move a set number of steps as I know 1 rotation is 5mm movement so 40000 steps should be 1000mm.by Desertboy - CNC Routers, Mills, and Hybrid RepRapping
She moves at least the gantry Powered up the axis using the ramps board. All motor's are on and aligned to ballscrews, the dsg16 (Ballnut mounts) are all bolted in as well and if you turn the couplings everything moves.by Desertboy - CNC Routers, Mills, and Hybrid RepRapping
Tried to spin the motor's up today using a cnc shield connected to 12v pc power supply, the nema's made a ticking sound but no more, what could be wrong? I spun them up using my 3d printer before I fitted them into the machine connected to a ramps board and all 4 worked fine? Tempted to drag the printer to the machine and try with the 3d printer electronics instead. I couldn't try adjusting thby Desertboy - CNC Routers, Mills, and Hybrid RepRapping
Quoteo_lampe You can get away without precharge circuit, but don't be cheap on the on/off switch then. This is what I was eyeing up for an on/off switch Or Both cheap lol. Z axis is almost finished now need to drill the spindle mount, the spindle mount will be bolted with 3 m4's per side directly through the top Z axis plate and into the Hiwin's An early project will be remaking the Z aby Desertboy - CNC Routers, Mills, and Hybrid RepRapping
Quoteo_lampe Wow, this PSU looks huge. The capacitors will be a challenge to switch on. Is there a precharge circuit planned? I wasn't going to because I didn't know I needed one, will ask on the other forums where I found people building their own. I know a couple of people have built identical power supplies to one I pictured and they're working fine years down the line.

Z axis is getting there but need more bolts waiting for delivery. Energy chain wasn't as hard to mount as I thought need to connect it to the z axis. No way are the water lines going inside the energy chain. This is from Joe's excellent build thread I've had the parts delivered this morning will build up mine at the weekend 68v's of goodness.

Self build PSU cost £90 in the end but it should be plenty beastie when built and give me ~68v and 12amps in an unregulated power supply. This is from the AM882 (Stepper driver) manual "6.

I didn't want to use Fusion 360 because I've been a linux fan boy for a long time but I've started to use it and it's really good.
