Building a SplineScanner or BookScanner? Using one, made it better? Your RepRap is a scanner? You just use a (video)camera to scan things? You make your own telescopes? Talk about it here.
Re: PIC firmware - 17 years ago
Thanks. I went to try and checkout the SVN firmware folder (under ) using Eclipse and I came up the error: svn: Processing PROPFIND request response failed: required string: "lp1:version-controlled-configuration" (/svnroot/reprap/!svn/bc/906/trunk/reprap/firmware) svn: PROPFIND request failed on '/svnroot/reprap/!svn/bc/906/trunk/reprap/firmware' I've previously got the host software fineby reece.arnott - RepRap Host
Re: PS: Opto endstop 1.0.1 - 17 years ago
Just connected the opto-stops to the rest of the electronics and answered my own question: the keyed 3 pin header on the opto-stop boards should go in the same orientation as the one its connected to on the stepper controller board i.e. with the key facing towards the center of the board. And wouldn't you know it, I had it the other way round. Its quite easy to tell as when you plug in the Min oby reece.arnott - Controllers
Re: PIC firmware - 17 years ago
OK. I'll have a poke round when I get home but it sounds like its probably just easier to leave it at the moment until Adrian finalises his changes. The main reason I want it now was so I could have all my circuit boards hooked together, tested, and working with nice blinking lights. So far I've got X,Y, and Z stepper boards all hooked up and working perfectly so I'll probably just leave it atby reece.arnott - RepRap Host
PIC firmware - 17 years ago
If I remember there was some talk about how the extruder.hex file just needed one or two bytes changed for it to be used as for the 2nd extruder. I can't find the thread but could someone tell we what changes need to be made? Or even better, re-release the firmware on sourceforge with the correct files and maybe even a little readme saying what each one is used for. I also notice that the namesby reece.arnott - RepRap Host
Re: First (basic) attempt at a repstrap - 17 years ago
I was going to suggest you post the details of exactly which lego kits and parts you used but then I re-read your post and as you're probably not going to evolve it into a reprap it may not be worth the bother (I think it would probably be a lot of work to document from looking at the pictures). Having said that, I for one would be interested in having a closer look at your support structure toby reece.arnott - General
PS: Opto endstop 1.0.1 - 17 years ago
Just finished soldering the components into the Opto-endstop boards and came across some other issues: 1. The silver circles around the R1 and R2 holes for solder to stick to are smaller than normal (I'd say too small). 2. The holes for the 3 pin header to plug into are even smaller than normal. It took too much force to put them in. Some of them had the pins slip through the keyed plastic bit sby reece.arnott - Controllers
Opto endstop 1.0.1 silkscreen error? - 17 years ago
Just doing the opto-stop boards and the silkscreen on the ones I have (v1.0.1) have R1 as a 10K resistor at the edge of the board and R2 as 220 by H1. Looking at the documentation and pictures it seems as if the silkscreen has the labels R1 and R2 around the wrong way. i.e. R2 is the 10K at the edge of the board and R1 is 220 by H1.by reece.arnott - Controllers
'Magic' bolt length? - 17 years ago
I'm hoping to finish off the electronics this weekend and am looking into a major shopping trip in the next few weeks to gather together most of the non-RP'd parts to build the Cartesian framework and came across the comment on the DarwinConceptsImprovements page saying that: 'Magic (single) bolt length would be cool'. I totally agree and was wondering if anyone has done anything about this or aby reece.arnott - Mechanics

Questions and comments about Stepper and Extruder boards - 17 years ago
Over the weekend I put the final touches on my UCBs and tonight I started the job of differentiating them into Stepper and Extruder boards (version 1.2.1 of the UCB ). First I had to get myself a PIC programmer. I looked around and found a Velleman P8048 KIT for sale on TradeMe (New Zealand version of EBay) by a guy in town so I got it.

Re: PowerComms 1.3.0 preview - 17 years ago
I have absolutely no idea how hard this would be from an electronics point of view but I'll just put it out there to get shot down anyway: The power would be better if it alternated G +12 G +12 so that you can use 2pin headers and connectors and easily swap out faulty power leads and it also makes them easier to keep track of and less wire tangle as well. In my case I've made them from 2 differby reece.arnott - Controllers
Re: Universal Controller v1.3.0 - 17 years ago
I've just made up 4 Universal boards in a one-man assembly line (up to the power test point) and the only comment I have to make is to take back a comment I made in the past about the size of the holes for the 2 pin and 3 pin header. I had previously said they were too small (actually its literally because its square pegs, round holes). Now that I'm used to the amount of force needed I find it aby reece.arnott - Controllers
Re: how far is everybody? - 17 years ago
I'm just in the process of putting the boards together and hope to get the to cartesian robot and the extruder heads within the next month or so. Current issue is the PIC programmer. Are there any plans to make this one of the boards you can buy through RRRF?

First impressions of Stepper Tester and Stepper Board - 17 years ago
On the stepper tester 1.0 boards: It would be good if the header/link on the RepRapOneDarwin page was labelled "Stepper Tester v1.0 - Optional" to obviously signify that you really need this except for allowing good debugging. The instructions don't have a linked BOM as do the rest of the instructions. The pictures should be updated to show the stepper tester board rather than the stripboard vby reece.arnott - Controllers
Ubuntu Feisty USB -> serial adapter issue - 17 years ago
I just had a frustrating hour or so trying to communicate with and test my powercomms board. It turns out I was the victim of a known issue in Ubuntu Feisty Fawn. As I'm sure a signicant portion of us are using Linux and the majority of those seem to have some version of Ubuntu I thought I'd make you all aware of this : .

Powercomms board first impressions - 17 years ago
I've just built my very first board (only burned myself once with the soldering iron :-) so I thought I'd give a bit of feedback: The board is the 1.2.1 version of Powercomms board and I got the board from the RRRF store with the components coming from Mouser using the generated BOM. 1) In the instructions it has the line "8) 4 pin power connector - diagonals towards bottom of board, not top. sby reece.arnott - Controllers

Re: Next Steps - 17 years ago
About the bounty Zach mentioned: why don't we pool resources and each put in a little for the winner to take ...

BOM spreadsheets - 17 years ago
I've just been looking at the BOM spreadsheets and found they are a little less useful than I'd been lead to believe from the chatter around here. The unique parts sheet contains all the parts codes for the various sites but the individual spreadsheets just contain a description and the quantity. Obviously this is so you only need to keep one set of part numbers up to date but it seems that thisby reece.arnott - General

Re: PowerComms power out. - 17 years ago
I was thinking that the transition to USB from serial was (in part) to enable the use of power-in over the USB port. Then we can do away with the power supply altogether and have eg. RJ45 power over ethernet connections from the power/comms board. Did I pick something up wrong, or did I just have a good idea at some point? Then of course you get further away from having the standalone machine tby reece.arnott - Controllers
