Righto then .... a few days off and a couple of days furious wiring and soldering have yielded a nearly ready to roll Mendel90. I reckon I've spent more hours on the wiring than the mechanics! I stuck with the ribbon for the head stuff but have gone for discreet wires for the bed - still using the "cable chain" idea from Nopheads design. For everything else I've loomed the wiring that came suppliby 41southrap - New Zealand RepRap User Group
It happens to the best of us! Welcome aboardby 41southrap - New Zealand RepRap User Group
Thanks Bert, that OpenBeam is next on my list! So, not a lot happening on the build over the last couple of days. I've had to email Chris (Nophead) re a couple of things that have cropped up but I think we have sorted those out. The big one was some torsional twisting of the X motor bracket which was causing the T5 belt to run out to the end of the pulley as the carriage moved back and forth.

One last update for the day A few things popped out of today's work. Things such as making sure that the pointers on the threaded shaft don't fall under the couplers before you tighten them because then you have to take the whole coupler apart again and put it in the right place! I had a slight issue with the width of my T5 belts which meant that I had to (a) put an extra 4mm washer into the Xby 41southrap - New Zealand RepRap User Group
Nice, maybe I'll make one when I finish the Mendel90by 41southrap - New Zealand RepRap User Group
After a major day of building - and 2 trips to Anzor for either stuff I got wrong or they got wrong - all of the major components are coming together. It doesn't look much in the picture I haven't yet sourced M8 brass nuts for the lead screws but I talked to the guys at Anzor and picked up some Prolan anti seize grease to see if that works ok with the stainless nuts I have. Changing to brass woby 41southrap - New Zealand RepRap User Group
Does anyone have a hobbed bolt I could buy? I also need a J head if anyone has one for sale (mkV-B if possible). I was thinking 0.4mm size and running 3mm filament - any comments from the group?by 41southrap - New Zealand RepRap User Group
I now have the new bolts, so that issue is solved. The courier arrived today with the steppers from Aliexpressby 41southrap - New Zealand RepRap User Group
I struck a minor issue when I was putting the Wades together. I found that I had ordered cap screws rather than hex screws so the heads sit proud of the holes and will probably interfere with the motor mounting. Back to Anzor - Bunnings didn't have the right lengths in 4mm.by 41southrap - New Zealand RepRap User Group
Thank you very much kind sir. Seems that my next challenge will be learning that piece of software.by 41southrap - Mendel90
Does anyone have a photo or render of how the Y idler goes together? I can't quite imagine where all of the M4 washers fit. 3 are reasonably easy - but the other 2 not so, unless inside the idler is something like ..... 4mm washer -- 5mm washer -- bearing -- bearing -- 5mm washer -- 4mm washer ??? Excuse the crude "drawing"by 41southrap - Mendel90
I'm banking on the fact that the bed is clamped to the glass (and that the glass won't warp too ) Thanks for that tip on lining up those bearings too The Nophead design uses a ribbon cable to get power etc to the bed. It looks like the picture below (linked from Nopheads web site) when it's finished (I had the carriage upside down when I took that photo). And mocked up using a piece of heby 41southrap - New Zealand RepRap User Group
Started the build yesterday, I have the major frame pieces together, along with the bed cooling fan and a temporarily mounted Arduino mega. I've just finished the 'pre-construction' of the y carriage - 'pre' being everything in place and ready for final fitting and adjustments. This is sure a learning curve, trying to work out the 'what bit goes where' stuff is a challenge at times, but betweenby 41southrap - New Zealand RepRap User Group
Email matt@watercut.co.nz They are based in Miramar here in Wellington. They were going to do my complete frame cut from 10mm and 6mm acrylic for about $145.00. It's a fantastic machine to watch operating. If you can email them a dxf file they'll price the job via email for you.by 41southrap - New Zealand RepRap User Group
As a newbie the ramps 1.4 with lcd is what I've gone for. Purchased from fabster3d via eBay. Shipping took about 3 days to NZ!by 41southrap - New Zealand RepRap User Group
I can put you in touch with a water jet cutting service in Wellington.by 41southrap - New Zealand RepRap User Group
Shoot him a pm Craig. The Fedex man and courier arrived with more bits today. I'm pretty sure I only ordered the electronics on Monday! Damn I'm going to have to get building now. I noticed a small amount of warping of the heated bed pcb - will that be an issue?by 41southrap - New Zealand RepRap User Group
Nopheads shipping is very cheap, just contact him and place an order. I don't think you'll see much savings in a multi order. Found my springs at Bunningsby 41southrap - New Zealand RepRap User Group
Thanks guys. Hylton didn't have them in the catalogue but I'll give them a ring today and see what they have. Bunnings - ah yes, my second homeby 41southrap - New Zealand RepRap User Group
Anzor will have all my bits and bobs ready tomorrow to pick at 9am. Have ordered the T5 belts via Trademe and the LM8UU bearings are in the post - as are the steppers from AliExpress and the electronics from Fabster3d. So now it's all hurry up and wait for the post Still looking for M5 x 20mm washers if anyone spies any. I also need springs of the size 12mm OD x 0.75mm gauge x 10mm long (1 of)by 41southrap - New Zealand RepRap User Group
Hi Bert, Thanks very much for the offer but I decided to build a Mendel90 instead. That build is progressing well. Cheers Colin.by 41southrap - New Zealand RepRap User Group
Will do - thanks Wired1 Just bought my motors from Aliexpress and purchased a whole suite of electronics (including a mk2a heated bed) from eBay via 'fabster3d'.

The hobby room had a double booking with the sewing maestro yesterday, so the pictures had to be taken in the dining room Just a note too - when I went to buy a 4mm tap the folks at Trade Tools recommended a machine tap to me, so I could put it in the battery drill. That made the job nice and quick and very easy. Also the material I'm using is Plexiglass - not sure of the difference between tby 41southrap - New Zealand RepRap User Group
Spent the afternoon drilling, taping and cutting. The result is very pleasing indeed I'll be waiting a few days for a shipment of hardware from Anzor, so in the mean time I've done a test build of the frame with some 4mm plastic screws I had in the junk pile. The rest of the parts are just sitting in place for effect. The strange angles in the picture are just a result of the phone picture I tby 41southrap - New Zealand RepRap User Group
Quick update; After finding a chuck for my Dremel yesterday I have drilled all the pilot holes, hopefully today I can do the final hole sizes and tap them. Just purchased 10 x lm8uu for $2.40 ea via Trade Me - seemed like a good deal. Placed an order via the Anzor web site for all the nuts/bolts/screws/washers. They had everything except the M5 x 20 washers - so if anyone has a supplier for thby 41southrap - New Zealand RepRap User Group
Drilling plans printed, joined and now taped to the acrylic ready for drilling. I think this is where I cross fingers that I've aligned it all properlyby 41southrap - New Zealand RepRap User Group

My printed parts arrived just now - thanks heaps to Mr and Mrs Nophead This includes the Wades extruder parts. Sending the steel off to be cut today and ordering all of the rest of the vitaminsby 41southrap - New Zealand RepRap User Group
