Re: Funded Bounty: Create a configuration tool for RepRap firmware - 10 years ago
Firstly I apologise for the lack of updates recently. I'm approaching the end of my Year In Industry (A year out from University to work) and things are a bit busy as I try and finalize work. After next week I'll have just over two months to do whatever I like. This firmware config tool should be one of those things. I like the idea of pulling in EEPROM configuration settings. Also I'm thinkingby samp20 - Bounties

Re: Mould for a glass art project - 10 years ago
Unfortunately it was printed in PLA, so acetone would not work. I have just created the clay moulds. The roughness wasn't an issue since the cling film I used to stop the clay and plastic sticking also smoothed over the surface. If there were any rough parts then I just smoothed them by hand.by samp20 - Casting and Moldmaking Working Group

Mould for a glass art project - 10 years ago
My landlady has her own studio and kiln for creating glass objects such as bowls, vases, sculptures etc. I thought it would be interesting to try and use a 3D printed mould to create a clay mould to slump glass onto. I came up with the following simple design to try out (created and rendered in blender): I shall post more pictures as I progress with the idea.

Re: Idea for full color FFF/FDM printing? - 10 years ago
I tried the above idea and ended up popping the resistor. Funnily enough, when the resistor did pop I got a tiny bubble of steam on the top surface. I think I need to try a lower power, but longer duration next time. When the resistor blew I was using approx 6W pulses of 1ms, with an interval of 1 second between pulses. The resistor did not blow straight away though. It took 10 or so pulses beforby samp20 - Developers
Re: Idea for full color FFF/FDM printing? - 10 years ago
I've been experimenting with various designs, and unfortunately haven't managed to get anything to work. I even tried replicating Adrian Bower's design . I think my problem is my voltages are too low. Adrian was using around 100 volts to get his to work. At most I was using about 30V. I've had another idea though. Would it be possible to use a low value surface mount resistor to rapidly boil theby samp20 - Developers
Re: Metal Printer - 10 years ago
Since you're not willing to give details I'm going to make a guess at how you're considering to do this (please don't take this personally, I just enjoy speculating). In your post you said: QuoteSethEden ...as a fine metal wire is much better than a thick metal wire for metal printing with this process... This makes me think you're planning some sort of welding process, i.e. where you apply a volby samp20 - Developers
Re: Modified CoreXY - 10 years ago
The red can collide with itself on the left, and the blue with itself on the right. Only when the carriage moves to the top in the image. All that being said it may be a non issue if your belts are thin enough (e.g. GT2) since the rest of the frame, linear rails etc would be the limiting factor. You would have to model it to scale to see if it's a problem or not. Edit: QuoteMrDoctorDIV Edit: Iby samp20 - Mechanics
Re: Modified CoreXY - 10 years ago
QuoteMrDoctorDIV So I think I just found what is possibly a better modified CoreXY. Observations? I was about to say yours was better since it is a simpler design on the X-ends. I drew up the fixed version (a bit scruffy as it was done on my phone) and noticed another problem unfortunately: I've highlighted 4 areas in green where the belts can collide. I think that's why the design you linked usby samp20 - Mechanics
Re: Modified CoreXY - 10 years ago
Sorry about the earlier mistake, and thanks for fixing it A2. For belts vs string, I think belts would have the advantage in your case. With line/string you will need to wrap it a few times around the motor pulley to minimise slipping. This will mean that your string will not be inline with at least one of the other pulleys. Also as the motor turns the string will move up and down the motor pulby samp20 - Mechanics
Re: Modified CoreXY - 10 years ago
In the 2nd image the rightleft-blue and leftright-red belts need to be perpendicular to the X axis. That can be fixed by just moving the top two pulleys closer together. Edit: sorry about the typo. I really should avoid posting late at nightby samp20 - Mechanics

Re: Funded Bounty: Create a configuration tool for RepRap firmware - 10 years ago
QuoteTraumflug Quotesamp20I'm not sure if using python 3.3 (or later) and a dev version of wxPython is going to cause issues. What makes you feel the need to live on the bleeding edge? I guess a configuration tool isn't exactly rocket science on the GUI part, so I'd expect it's quite possible to live with the same dependencies Pronterface has.

I've made a few comments on the bounty page itself, although it's probably worth me posting here too. I have a WIP configuration tool using python 3.3 and wxPython Phoenix on my Git page: .

Re: Recent Threads - 10 years ago
Yes I know about the red text on the start page. It's still takes a little while to load and visit each of those pages, then mark everything as read (for those topics I don't visit). My original post made this sound a lot worse than it is. The RSS feed should allow me to view all recent topics in one go, so consider my problem solved. I'm not sure if this solves the issue for tjb1 also.by samp20 - Administration, Announcements, Policy

Re: Using 3D printing in non-hobby purposes - 10 years ago
I encouraged our workplace to buy an Ultimaker 2. We now use it to create mechanical supports when testing phones and development PCBs that use our chip. Also we make misc clips, holders etc similar to @bryanandaimee. We would bodge things with BluTak and anything lying around otherwise.by samp20 - General

Re: Lautr3k, a V-Slot and LeadScrew RepRap - 10 years ago
great build, and runs very smoothly. Would you consider your machine rigid enough for some light milling e.g. PCBs? I tried myself to make a leadscrew reprap. Unfortunately I had a few resonance issues and since switched the X to belts. It's good to see someone like you get it rightby samp20 - Extruded Aluminum Frames
Re: 3D cement printer - 10 years ago
With the Kisslicer problems I think the reason might be that Kisslicer uses a bitmap internally for insetting the perimeters. For large objects this bitmap becomes too large.by samp20 - General

Re: Wire all negatives in one? - 10 years ago
@Ralph very good point. To clarify further the negative of the heated bed/hotend is connected to the drain of the MOSFET. The source of the MOSFET then connects to ground. If you're using a board such as RAMPS etc then the MOSFET ground is already done on the PCB. Here's a diagram I found that should clarify: Ignore the 1N4001 diode as this is usually for more inductive loads such as solenoids.by samp20 - Developers
Re: Wire all negatives in one? - 10 years ago
The other thing to be aware of (you may be already) is the ground needs to be able to handle the total current of the heated bed etc. As long as your wires are thick enough there should be no problems.by samp20 - Developers
Re: Idea: A RepRap Hanging From the Ceiling - 10 years ago
How about a comprimise between 1 and 2. A sprung loaded Z motor. You then don't have to worry as much about getting all 4 motors perfectly in sync. I love where this idea is going though. I can just imagine having to duck under the cables whilst a print is ongoing in the middle of the roomby samp20 - Delta Machines
Re: Idea for full color FFF/FDM printing? - 10 years ago
You would need to be careful not to heat the ink up too much otherwise you could end up drying the ink out and clogging the nozzle. I think Pacaus' idea of mounting the inkjet next to the nozzle but separate is the way to go. Apart from getting a working inkjet in the first place, there is also the challenge of fitting it all onto the X-carriage. If we get really stuck for space then this (or anby samp20 - Developers
Re: Idea for full color FFF/FDM printing? - 10 years ago
I don't know where the piezo was from. I salvaged it from a plastic enclosure. It is 32mm diameter if I remember correctly. I'm powering it from between 24-36V from my bench power supply,and switching it through a suitably rated mosfet. I have a 10kohm resistor in parallel with the piezo to relax it after firing. I haven't tested the electronics with the completed assembly yet.by samp20 - Developers
Re: Idea for full color FFF/FDM printing? - 10 years ago
I have made a little progress with this idea. I've 3D printed an inkjet which uses a piezo element to compress a chamber. I'm currently unable to test the electronics (visiting parents for the week), but I found a light tap of my finger on the piezo element was enough to eject a little water (Ink testing will be later). I've attached an image of the assembly. The nozzle was made by inserting aby samp20 - Developers
Re: RepRap Interface Standard - 10 years ago
@JustAnotherOne, I have a few arguments to put forward against your suggestion: I am not aware of anyone using the VCC, Signal, GND standard. We would end up with 3 configurations in use instead of the current two: Signal, GND, VCC and Signal, VCC, GND The Signal, GND, VCC can still work with mechanical endstops since they connect between Signal and GND.
