Spot: FESTO's iFab - 15 years ago
I'm interested in your thoughts on this. A friend pointed me to the following URL: I can't help but think that there is quite some inspiration from various RepRap parts. Especially the screw/filament holder. Interestingly a tripod platform was chosen, which was also evaluated for the RepRap. By Viktor: I must say that it is used very elegantly.

Re: Firmware Modifications for Pinch-Wheel Extruder - 15 years ago
I'll see if I can replicate it. Maybe today. I guess we could come up with a fix then. I've been looking at the firmware a lot these days, because I also think I had the problem with the extrusion was >= STEP_EN_PIN while I set it to -1. This meant for me that stepper based extrusion kicked in. This setting was historically a compiler-level variable, but now it is set at run-time when the progby ErikDeBruijn - RepRap Host
Re: Pocket Pc / Windows CE Host For Gcode - 15 years ago
If I can get one at the same price range I'll definitely get myself a different device! I could find one at around 50 euro's, slightly too expensive for a device introduced > 4 years ago. I'm actually looking for something with WIFI. I assume there's no full usb plug on the toshiba PDA. How do you get USB off it? Do you use the USB cable that normally goes into the PC (host) and use it the otby ErikDeBruijn - RepRap Host
My firmware modifications: feedback and arduino IDE testing support - 15 years ago
I've gone through a lot of trouble finding out why the trunk g-code interpreter hung, because I never got anything back from it. Everything appeared to run fine. Eventually it appeared that the \n isn't added when you use the arduino IDE (0015)! This wasn't the case for Zach & Marius Kintel's branch that handled buffering. Anyway, if you still want to be able to issue manual G-Codes, changeby ErikDeBruijn - RepRap Host
Re: Firmware Modifications for Pinch-Wheel Extruder - 15 years ago
What version of the firmware were you using and intending to modify? Of a user (Zach, Marius')? Or of the main one (mostly managed by Adrian IIRC)? In the svn trunk (reprap/trunk/reprap/firmware/GCode_Interpreter) there is code in there for stepper based extrusion. For example in parameters.h(.dist): // For when we have a stepper-driven extruder // E_STEPS_PER_MM is the number of steps neededby ErikDeBruijn - RepRap Host
Re: Pocket Pc / Windows CE Host For Gcode - 15 years ago
I set the baud rate correctly each time. This is not the problem anymore. I get bidirectional communication on COM1, but the stopbit is wrong (should be 1 for 8n1), so the characters are not normal ascii codes. When I use stopbit 1 it doesn't work ("Unable to open connection to COM1:") I'm a little bit stuck here. I guess it has to do with the request to send (RTS) that will not be ignored by tby ErikDeBruijn - RepRap Host
Re: Pocket Pc / Windows CE Host For Gcode - 15 years ago
Hi Mike! I see the interface is a lot better now. I like how it's full screen and everything fits. I can't wait for the progress bar to actually display the print progress! For now I'm still stuck with the comms problem in putty. I'll try another terminal. First I'm going to cook a meal!by ErikDeBruijn - RepRap Host
Re: Pocket Pc / Windows CE Host For Gcode - 15 years ago
I made some progress: 1. I had to turn off receiving incoming beams. 2. It was COM1 after all. 3. Stopbit=2 gives garbage. It is garbage at the correct interval (test program that outputs a few lines). Stopbit=1 won't open the COM1. I see (just now) that you have a new release again! I'm going to try it now! B.t.w.

Re: Pocket Pc / Windows CE Host For Gcode - 15 years ago
Hi, ActiveSync is not in 'my running programs'. I've been trying all kinds of baud rates and COM port numbers to no avail. I used a known-to-work GPS device. Also, I use 8 data bytes and 1 stop bit (it works with this setting under linux). Then I went searching. From this linux kernel boot on the HTC Blue angel (my device) I got this: <6>[ 1.400000] TI Calypso / HTC firmware GSM UARTby ErikDeBruijn - RepRap Host
Re: Pocket Pc / Windows CE Host For Gcode - 15 years ago
Hi Mike, I just made a cable that should (in theory) work. But now it says "Port not available or already connected". I can only choose COM3, which could be right, but it could also be another port. When I try to run a manual G-Code, after +/- 5 seconds it says "Comms error". I cannot differentiate this result from when it is not connected at all.

Re: Pocket Pc / Windows CE Host For Gcode - 15 years ago
Program runs fine! (already had a working .NET 2.0 version, apparently) I must say that it's already a very decent app! I can load gcode and I've configured it. I need my car to get the cable. Hopefully my girlfriend will be home with it soon. Meanwhile I can work on rewiring the machine. I had made an SPI SD card reader that is no longer needed now. This solution is far betterby ErikDeBruijn - RepRap Host
Re: Pocket Pc / Windows CE Host For Gcode - 15 years ago
You're quick Mike! I've put the files on an SD card to try them, but I'm still waiting on a charge. It's been in a drawer for quite a while. If I get it running I'll make a cable and see if I can actually use it to 3D print something!by ErikDeBruijn - RepRap Host
Re: Generation 3 Electronics - 15 years ago
I've added a link to the 3rd gen electronics page with a notice that it is still under development and hardly used in the field, mostly for that reason. To me, it seems almost ready for prime time and already would be a feasible option for some. SMT seems hard to many, as it did to me, but I was able to solder the magnetic rotary encoder without flux or a hot air gun, tweezers or the reflow methby ErikDeBruijn - RepRap Host
Re: Pocket Pc / Windows CE Host For Gcode - 15 years ago
It's not a smartphone but pocketPC / WM5. Cool @ COM detection! Seems like a fully fledged host! I only need it to feed the machine with G-Code, no fancy gui stuff needed IMHO. Yet it could display a web-page with a picture of the layer being built, or anything for that matter that you wish to send from a PC. It would also be great if it could poll a page to download G-Code (from a HTTP based 'pby ErikDeBruijn - RepRap Host
Re: Pocket Pc / Windows CE Host For Gcode - 15 years ago
Cool WM5... I guess that's WM2005, right? I assume there's some backward compatibility, so you might compile it for an older version for wider support? It would be COM5 or COM7 if I recall that would interface to the GPS. That would be the UART I can probably use.by ErikDeBruijn - RepRap Host
Re: Pocket Pc / Windows CE Host For Gcode - 15 years ago
Ah, good old qbasic. Used that 12 years ago to learn to program when I was 14 years old. I guess it should be easy I don't have windows, so I guess I still need that and need MS virtual studio etc. I've got so many IDE's already, Netbeans, eclipse, arduino, etc. I'm hesitant to invest in yet another, and I prefer a completely open environment since most future phones will support Android/Linux,by ErikDeBruijn - RepRap Host
Re: Pocket Pc / Windows CE Host For Gcode - 15 years ago
Excellent. I had been thinking about using pocket PC's to get a more fully featured interface at low cost. I don't have any .NET knowledge, however, so I didn't get to that (and probably never would have!) I like your solution a lot... this means that you'll have a color screen and a PC independent RepRap and (in my case) you can use your old smartphone for this.

Google Summer of Code - 15 years ago
Hi, Shouldn't we participate in ? I would have done this, but I hope to graduate before summer! I really thing that RepRap is an amazing project, also different from all the other open source software... so we're a distinguished program. And also I think that RepRap is one of the open source projects that really can (are) have(ing) a big impact on the world.by ErikDeBruijn - RepRap Host
Re: SD read write tutorials? - 15 years ago
Marius, nice hack! I look forward to trying to replicate your results. I'm looking for the mini-SD-card component (to put the SD card in). I prefer the one that is compatible to Zach's RepRap Motherboard (which you also seem to be using). I was intending to have a couple of them manufactured. It seems Zach has already had some produced?! I'm very interested in using a motherboard due to the cleby ErikDeBruijn - Controllers

Hey Dries, Heb even contact opgenomen over reprap.nl. Mogelijk willen ze hem een nieuwe beheerder geven die de site weer nieuw leven inblaast. Het zou leuk zijn! Misschien kunnen we dan ook Nederlandstalige documentatie op gaan zetten, hoewel dat dan wel goed onderhouden moet worden (kan voor reprap.be en reprap.nl samen, natuurlijk).

Re: Increasing Accuracy - how? - 16 years ago
Tony, I think many people at first think that a lot of things can be done better. There is a lot of work to be done for to create a 3D printer, so in a sense you're right. But the funny thing I noticed is that I started learning about the reasons things were done simpler than you would expect. You start to understand where the trade-offs come from. I'm sure you could contribute to the project wiby ErikDeBruijn - Plastic Extruder Working Group
Re: Polypropylene - 16 years ago
Tony, you have a lot of good results to show of. They don't need to be perfect according to your standards I'd also really like to see a wide range of plastics being supported by a RepRap. It really beats the hell out of the limited set of stratasys materials (al though you can order many colors and some variations, it's all very expensive).

David, that would be helpful! I expect to be using advanced features, but starting off with the simple parameters and having good defaults makes it less daunting.

Re: I'm writing new software which you might like - 16 years ago
Hi Brian, I commend your work and intention to open source. What you develop proprietary is totally up to you. I understand the decision you're facing. Developing open source software is socially functional, but since you must feed yourself it is usually not individually sustainable to ONLY develop open source software. In a perfect world, society should sponsor people that do community work.by ErikDeBruijn - RepRap Host
Useful for new liveCD/DVD /w branding? - 16 years ago
Hi, I just found this piece of software. It might be a nice tool to quickly make a liveDVD/CD. We can even brand it nicely with the RepRap logo: Perhaps it would be best to make an Ubuntu package for the RepRap toolchain first. For anyone with the debootstrap knowledge to make a package, I can give a login to a server that we run for the RepRap project. It already runs apache (LAMP setup). Weby ErikDeBruijn - RepRap Host
