Re: Required tolerances on frame alignment - 9 years ago

Hi, That's a very interesting question and I would really welcome some informed comments on that, since I am also putting together my Delta Steel prototype these days and facing the very same issues. I believe column angle errors will become more significant the further you print from Z=0 which is the height for which you will calibrate your printer. Correct me if I am wrong, but a quick calcu

Re: DRV8825 Can't set 1/16 stepping - 9 years ago

Yes it's a typo. 1/8 is the line between 1/4 and 1/16. BTW my DRV8825 "made in China" drivers have been working perfectly at 1/32 microstepping - but I have no complaints about the A4988 ones at 1/16. Both types work well for me.

Re: prusa i3 vs fa)(a vs hbot, quelle est la mieux pour débuter ? - 9 years ago

Ah OK, et c'est bien vrai que pour juger de la qualité d'un kit il faut de vraies photos des composants, sans quoi... C'est d'ailleurs le problème de la plupart des kits: la qualité est très variable. Bien que débutant je préfère acheter les pièces séparément, on a un peu plus de choix au niveau du prix et qualité qu'on veut avec les contraintes d'un budget limité. Dans le cas de la P3Steel la

Re: What's the difference between the wades extruders? - 9 years ago

@ Lenbok Thanks for pointing that out, I'll take a closer look at the OpenSCAD source code when I have some time. In any case, the idea for the renders is more to give the reader a visual means of checking the evolution of the extruder, as in this case a picture is really worth one thousand words!

Re: Strange heatbed heating problem - 9 years ago

It's possible the heatbed PTC fuse in the RAMPS could be acting strange. You can check the voltage effectively reaching the heatbed while 1. heating and while 2. printing, if there is indeed a big difference then it's the fuse. Replace with a fuse holder and a fast automobile fuse rated 15A.

You have to remove two jumpers to get 1/16 microstepping on the DRV8825.

Re: Prusa Mendel i3 - Parts and blueprints location - 9 years ago

Nathan, The first thing you have to decide is whether you are going to build the original Prusa i3 (and if so, which kind: box frame or single plate) or one of its variants or a Prusa i3 kit. Obviously if you buy a kit the decision will have been made for you by the kit manufacturer. I am admittedly biased for the P3Steel version 2.01 since I designed it myself... The BOM is in the wiki Cheers,

and possibly the Arduino too... Unfortunately there is no reverse voltage protection on the RAMPS board. Sorry to say so, but basically you can throw out whatever was plugged into the RAMPS and restart from zero.

The page you linked to links to the Prusa Mendel design, an ancestor of the Prusa i3. The correct Prusa i3 home page in the wiki is here: And btw, there is a specific forum for the Prusa i3 if you scroll down in the home page of the forum, in the Machines Specific section. If this is your first RepRap build my advice is to buy a nice kit that got positive reviews either here in this forum or

Sure. Please note that I don't want to sound like the GPL police or anything, and this is not a criticism of your work.

Re: Adafruit ST7565 LCD and Ramps 1.4 - 9 years ago

Really, it's not that hard to read. EXP1 is perfectly readable. For Aux3 and Aux4, you have their pinouts in the RAMPS schematics and also they are clearly annotated in the board layout here: And you need not concern yourself with EXP2 since it's only used for the SD Card reader. In any case, it's a good idea to take a look at the code in Marlin for the pin assignments, you would have to do

Nice job, well done! I'll be trying it on an Arduino Due + hacked RAMPS combo I am putting together to drive my experimental delta. I am using DRV8825 with 1/32 microstepping on the hacked RAMPS. Do you use Eclipse or the Arduino IDE for compiling? And what do you use to upload the firmware to the Due?

Re: Adafruit ST7565 LCD and Ramps 1.4 - 9 years ago

Examining the schematics for the connector, there is a problem with the characters for AUX3 and EXP2 overlapping, but it's actually rather easy to figure out what the pins are and you can refer to the RAMPS 1.4 schematics and board layout. For example, VCC and GND on EXP1 come from AUX3. I believe the HW SPI interface on AUX3 is used on EXP2 for the SD card reader, the LCD serial data seems to b
