Five Years Of Outerzone
Ken Lighten replied to Dai Fledermaus's topic in Building from Traditional Kits and Plans
What plan on Outerzone was it Chris? -
tis done Ian, slightly modified

Forum members' new models: Let's see them.
Ken Lighten replied to Paul Marsh's topic in All Things Model Flying
It's really only the wings and the spinner that are toast, I'll have a look later and see if anything from the wings is salvageable, usually looks a lot worse than it is till the covering is removed. Maiden flight, not enough aileron throw, my bad as I thought that with the size of them it would have been plenty, but not at take off though!, never mind, my first re-kit for years. -

Still looks quite scale like! ☺️ -

I saw the wire holder that Ian Jones had printed and thought that it looked a relatively simple thing to have a go at designing with Fusion 360, so, using the principles in BobW guide in 'Fusion 360 for modellers' thread, I had a go! It works too! Quite pleased with myself! Ken

Excellent Bob, easy to follow and saveable for reference 👏

Great idea, I need all the help I can get! - I've been struggling through with it for ages
-
reference my previous post about the lack of adjustment on the short 'Y' belt this chap came up with these idler cogs for tensioning it if you dont fancy removing the stepper motor **LINK** Ken

After many attempts with varying dimensions it is quite possible/likely that the problem is the 3D design software I'm using as the printer seems to print downloaded parts and samples/supplied calibration blocks reasonably well. I'm using Autocad 360 which is recommended by several people, could be that my machine/computer/me combination isn't good, so any other good, 'I'm using this easily with no problems' design software that can be suggested that I could try? - preferably free but at least not in the major engineering company price bracket.

Nope, nothing like the M180 but thanks anyway Colin, if only it was as simple as that - I'm currently in a terminal spiral of Emails with Malyan - if I survive I'll report the outcome! Ken
-
Thanks Colin, I've Emailed the Malyan support but I'm not holding my breath
-
Not that I can see on the M180 Colin, there is a screen for calibrating but I think its for head alignment of the 2 extruders as the adjustable figures are not step related - You would have thought the Malyan website would be of help! there is a very good chance that its just me thinking like an engineer and not a programmer I feel another internet trawl coming on Edited By Ken Lighten on 07/02/2017 20:55:37

it would appear not having retried a Makerbot version of the axis model
-
Well that didn't work! - AARRGGH! does the printer steps per mm stay on the printer firmware as set by ReplicatorG? or do I have to find how to do it for Makerbot? I will not be beaten (yet!)! Regards Ken
-
Me again, one other thing I did find when staring desperately at my printer was that the short belt that drives the Y axis isn't tension regulated like the other 3 belts. On closer inspection I found that the tension is adjusted by the fact that the Y stepper motor is mounted using slotted holes which aren't long enough to take out the backlash fully. releasing the motor, attacking the slots with a fine round file and refitting the motor has taken all the backlash out - did this before doing everything in my previous post by the way Ken Edited By Ken Lighten on 07/02/2017 16:27:33

I THINK I may be going down the right path now after a lot of interweb searching!, using the ReplicatorG program that came with the printer, I loaded it into a desktop folder rather than into the program files (rightly or wrongly, but it seems to allow me to alter things when not in the program fies) I then opened the 'machines' file followed by the 'Malyan system' XML document, this has the steps per mm figures (takes a bit of faff to find it but it's there!) I then altered the 'Y' figures as per Colins advise earlier. I printed a block and it still exhibited the same dimensional discrepancy so I figured that the calibrated block would have been created using the old parameters so opened it in ReplicatorG and then saved it again as a new item on the SD card. Printed a calibration block and viola and quel surprise a 20 X 20 X 10 block hoorah!! with this in mind, I am currently printing an axis model created in Fusion 360 with a 100 X10 X 10mm arm in all 3 axis which is already dimensionaly out (checked during the print process) so will then repeat the process of changing the steps per mm to suit and then reprint it to see if it corrects OK, then ANOTHER axis model to prove the concept followed by a circular object to see if it too is correct. IF this is OK I will use this program and settings for my own designs and Makerbot for downloaded ones as they SEEM to print OK with it - phew! probably completely wrong! Ken

Galaxy Mustang P51D 1/6 Semi -Scale
Ken Lighten replied to Paul Coxon's topic in Build Blogs and Kit Reviews
I think they may be supplied so you have a choice for which model Mustang you are building, I think there was differences in planform at the inboard leading edge Ken -
looks lovely Mike

hi again, Thanks Ian and Colin, read that 'walkthrough' Ian, finally had a chance to look at the calibration, I've printed the 20mm block supplied with the software, noted the error ( 0.76mm undersize in Y) now all I need to do is find the firmware! - anyone tell me where it is hiding? (I've said before that I'm a bit lost when it comes to computer programming etc) is it on the printer or part of the slicer software? regards Ken Edited By Ken Lighten on 05/02/2017 16:28:29
