Hi folks, whats new?
Well its been a few months since my last post, and i been needing to update things.
Basically i am creating the Huxley MD (My Design) reprap machine with my machine, and also started to make a stepper struder for my makerbot - running mk5!
so there has been lots to talk about.
After heading to the makerfaire in nottingham, i spoke to jeanmarc of emaker shop, and saw the small huxley he was making, i liked it, and wanted to make it. I didnt like the design for the extruder, and i wanted a more recognisable extruder that has been used, therefore i wanted to use the makergear hot end.
Also i wanted to use different bearings, lm6uu for 6mm rods.
I designed the parts and a picture will be put here, but there are flickr pictures!
I also have bought some angel eyes from ebay to fit onto my makerbot and reprap - 90mm and 50mm diameter lights! VERY nice and a recommendation to all!
The makerbot has been upgraded to feature a stepper motor, and im waiting for the gen 4 stepper motorfrom makerbot to fit onto it and make it amazing :)
Looking at stewarts build, the stepper motor design makes FAR better quality prints!
anyways, im also trying to design a heat bed for the huxley 140mm by 140mm so that Jeanmarc can use them on his emakers he is selling, and i can have one for myself!
sadly the etch tank has become too full of copper, and therefore i need to dispose of it and start with a fresh ammount of acid. This is a complex process involving taking the chemical to a hazardous waste recycling facility! and costs!
anyways, thats a brief summary of whats been going on. Oh and i got woodworm in my room, so im hoping its not going to the makerbot!!!

regarding poaterobotics.co.cc - business card web address issue :(
After handing out many business card at Makerfaire UK 2011, it has become apparent that my registration for co.cc has expired as of 4 days ago.
Sadly i cannt log into my account and therefore people looking for it, it will not display.
If you are one of those people, please visit the original hosting address of:

this is currently being updated so please take a look and contact me for any info.

yay! dont you just love payday!
well, pay day is upon us, well its been a few days and aftre sorting out all my other bits ni need to buy, i decieded to put money towards a mk5 and a few other bit and pieces for the makerbot... so putting in my order, i am dreading the cost of uk import tax... estimate it to be about £50 so when it comes i will let you know, but... it has been ordered!
for some reason i cant add a pic... but the total cost was $259.70, thats about £158.
i got:
mk5 plastruder full kit: $185 (£114.42)
2 x lengths of nichrome to replace mk4 bits: $10 (£6.18)
frostruder mk2 experimenters kit - to use on my pcb smt setup: $20 (£12.37)
10 x 3mm gold magnets: $2.50 (£1.54)
and postage: $42.20 (£26.10)
we shall see! its been shipped along with some timing belts to replace the ones i have originally, they were open ended belts glued together with wet suit glue so will eventully break!
but yay,
need to also buy a new stepper motor chip...

Blue magic smoke :(
So, here it is... as im designing a shell for use in a project, which needs to be completed by Wednesday... for the MCM expo! Yes the MCM expo in london next weekend, i go to use my makerbot, and sadly the Z axis starts playing up... then a wiff, snap crackle and pop (and no mini cartoon characters to see for miles) the stepper motor controller decieds to frazzle.
Luckily when the first time this happened, i ordered 2 spare chips, so i can replace the chip, will just take time...
Here goes!

Building of wobble arrester and new cable
Well its been an eventfull couple of weeks.
firtly i decieded to change my usb ttl adapter for the makerbot to a 5v logic level, as apposed tothe 3.3v logic level one i was using. the idea behind this was that the switchover signal voltage could have been too low and therefore meant the data was not being sent at good quality. I was annoyed when i bought the first cable, as i was thinking it was a 5v level cable, but alas... oh well.
the first tests came as i was setting up the uni makerbot for a demo of high calibre... more on that in a sec, but i managed to start repg and the new software version, meaning i could import and manipulate the files stl etc in repg.
the first trial pieces were done using my pc desktop, an old pentium 4. (i now bought a i5 HP laptop, so yay!) I did wounder if the processing speed was too slow for the makerbot, and i think i might have been right...
anyway, my first prints using the 5v cable, turned out to be good. they were a corner bracket, to try simple shapes... and then the z wobble arrester. this is an amazing thing an im glad i printed it, as my sides are virtually wobble free (need a second one for other side of rear as that too is a bit wobbly...
anyhow, i printed these with great success, installed the wob arr and set to print something more complex. The gear set, recently uploaded seemd lie the perfetc vhoice.
link here :(insert link)
the results seemed ok, but the thinner smaller gear had to be height adjusted as too much plastic was comming out causing lumps. - this maybe because there wasnt enough time to cool befre the heater nozel came ploughing through, so need to work on 'cool' settings as mentioned in recent blog post elsewhere - should really write the links down!. need to adjust speed and extruder flow rate too, both adjust this issue.
right a picture...
or 2...
the L bracket, shows several wobbly edges so off to print the z wobble arrester...
the wobble arrested whilst printing
The wobble arrester works wonders, and if anyone needs to see why it is handy, check this video out of the one i installed...
with the wobble arrester installed, i made the gears.
picture too come.
