Re: Makerslide Aluminium Extrusions - 12 years ago
This could be nice! Any idea of the final price? BTW, where do you live? Would you ship to France?by fma - Let's design something! (I've got an idea ...)
Re: Extrusion multiplier very low! - 12 years ago
From a theorical point of view, is it possible to have the extrusion width vary a little bit, all other parameters remaining the same (by pushing more or less plastic, at the same feed rate)? How do we determine the limits?by fma - Slic3r
Re: Extrusion multiplier very low! - 12 years ago
I guess that it has a lot of dependent factors: extrusion speed, hot-end geometry (nozzle length), temperature, ABS quality... how can we deal with all these parameters? Do we have to make calibration for every case? According to you, what are the mandatory parameter(s) to adjust to calibrate the printing? Skeinforge seems to use width over thickness ratio and extrusion multiplier. Why has the aby fma - Slic3r
Re: Rostock Problem - 12 years ago
Johan said that he was modifying the firmware so it only needs the top endstops; maybe you are using a not-ready version?by fma - Delta Machines
Re: Rostock Derivative - 12 years ago
Very nice! I was thinking using similar structure. After my first tests with the original design, I will switch to yours, but I will also use MakerSlides instead of rods ; I hope to be able to use this DeltaBot for milling PCB as well.by fma - Delta Machines
Re: Painfull problem @ first layer - 12 years ago
I tried the ABS juice, yesterday: epic fail How do you put the juice on the glass? How much is needed?by fma - Slic3r
Re: Painfull problem @ first layer - 12 years ago
I only have a small current power supply, so I modified my heating bed to have a higher resistor. So I only get 65°C. I'm using kapton tape, and I clean it a little bit with acetone before each print, and I don't have any warping problems. As RustyPaint said, @100°C, it can be hard to remove the parts from the tape! But 65°C is fine. Carignan, are you using kapton, or do you print on the glass,by fma - Slic3r

Re: first layer ratio ? which effect ? - 12 years ago
I also use this feature all the time, especially when using very small layers (0.1mm): the first layer is set to 0.4mm. The latest release allows to enter an absolute value, instead of a ratio, which is very nice, and avoid me to change the value when changing the layer height.by fma - Slic3r

Re: Z axis don't go down - 12 years ago
Things are clear, now! This is just an undocumented feature Thanks for help, guys!by fma - Repetier
Re: Z axis don't go down - 12 years ago
@jcabre, I already tried to switch the stepstick, with no success. And as I sid, I don't see the pulses... @nophead, I tried to wired the Z- endstop to GND, and it works! But... The endstops checking is disabled in the firmware (as I also suspected such problem), and this setting works, because no other endstop stops axis whatever level they are (I tried to wired to GND or VCC, and the axis stiby fma - Repetier
Z axis don't go down - 12 years ago
I finally received my stepsticks, and I have a problem: all axis work fine, except Z, which can't go down (up ok). When I hit the down button (whatever distance I want), no pulses are sent on the step pin (I checked with a led). Any idea what can cause this? I don't have any enstop connected, and they all use the same config values in the firmware. Thanks,by fma - Repetier
Re: Rostock delta robot now printing PLA at 50 mm/s - 12 years ago
Great! Good job! Here is the 3D printer next generation!!! I'm one of these guys who started to build one I'm waiting for some parts, but I hope to have it running soon!by fma - Delta Machines
Re: M221 use case? - 12 years ago
That's a great feature! A slider in repetierHost, like for speed, would be very usefull tooby fma - Repetier
Re: Delta geomerty - 12 years ago
AFAIK, Johann wrote the python code before he made a dedicated firmware; the goal was to use a standard firmware. But I think there is something wrong in the script, as I had to modify it so it writes E values, and even with that, it does not work... I had a look at his Marlin modification, where he implemented the delta firmware (which then use standard g-code), and some values are pre-computedby fma - Repetier
Re: Delta geomerty - 12 years ago
BTW, here is a python script Johann wrote at first to convert G-code for delta geometry, and use a standard firmware: Don't know yet if he used the same approach in the firmware patch...by fma - Repetier
Delta geomerty - 12 years ago
Ok, let's start a new topic for the delta geometry. First, I'm looking at Johann's (Rostock delta robot 3D printer author) firmware modifications. I started a topic for that too: As soon as I have enough informations, I will continue here to see how implement this geometry in Repetier's firmware.by fma - Repetier

Rostock delta robot firmware - 12 years ago
Hi, I started to build the very nice Rostock Delta robot 3D printer: and I'm now having a look at the firmware. Johann, could you explain a little bit what are the main modifications you made in the Marlin firmware? I would like to use the repetier firmware, as is has very nice features, and the author is ok to add such modifications in the original firmware if we can get something workingby fma - Firmware - experimental, borrowed, and future

Re: Support for non orthogonal drive system (xy H-gantry) - 12 years ago
Thanks for your answer! Johann (who designed the Rostock delta bot¹) has already implemented something, starting from Marlin firmware: and it seems to work (fast enough). As soon as I have a fully functionnal delta printer, I will give it a try. But I have to admit that your firmware has some very nice features I would like to use. And as you started to implement different geometry, I was thby fma - Repetier
Support for non orthogonal drive system (xy H-gantry) - 12 years ago
Hi repetier, I just read in your new firmware annoncement that you now support "non orthogonal drive system (xy H-gantry)". Could you explain what it is? Does it mean that you re-designed your code to be able to support different types of kinematics, like SCARA or DELTA? I'm currently building a Delta bot 3D printer (mainly based on Rostock design), and I would love to be able to use you firmwby fma - Repetier
