Great. Thank you for the advice. The wire running from the PSU to the RAMPS board will be 14AWG silicone wire.

No, not at all. I did thank you for your post. Please see a 'copy and paste' "Thank you for this. Seeing as I am intending to run 2 mosfets, and a PSU only has 3 connections for outputs, could I run the outputs as follows. 1 output to mosfet for heated bed 1 output to mosfet for hot ehnd 1 output to the 11A input on RAMPS and then jumper this to the 5A input.

Re: RAMPS 1.4 and external mosfets - 5 years ago

Thank you for the reply. The Meanwell type PSU that I am using is rated at 30A. The heat bed is 220mmX220mm. It will be a standard hot end, an E3D bowden clone to be exact. Not sure of the wattage of the heater cartirdge. Just to be clear, I will be powering the heat bed and hot end off 2 separate mosfets (each connected directly to the PSU by 14AWG silicone wire). My question is about the pow

RAMPS 1.4 and external mosfets - 6 years ago

Hi All, I am planning on switching to a RAMPS board in the next week or so. I have a question regarding powering the board when using 2 external mosfets (one for the heat bed and one for the extruder). If using 2 mosfets how do I power the board? Do I need to connect power to both input blocks (5A and 11A), or just one? If just one, then the 5A or the 11A? TIA

Re: Prusa Mendel I3 Y-Axis Rods - 11 years ago

Thanks for the replies. The reason I ask is that in the wiki build manual is says "2x 400mm M10 threaded rod", but in the build thread at http://78.47.92.212/i3_documentation_pics/04-yaxis.md.html it shows using M8 washers and nuts on these long threaded rods. So I am not sure which rods to use. TIA

Advice on first printer - 11 years ago

Hi all. I am new to 3D printing and need some advice on a first printer. I have been looking at the Prusa I2 and I3, but don't know if there is anything else that I should be looking at. My main problem in the build will be sourcing the printed parts, as I don't have access to be able to print a set of my own. Any advice would be appreciated. TIA Darryn

Advice needed on printer for beginner - 11 years ago

Hi. My name is Darryn and I am from Cape Town, South Africa. I want to build my first 3D printer. I am looking to build one from scratch, so that I can learn as much as possible. For a beginner, what would be the best printer to start with? I know there is a lot of support for the Prusa I2, but now that the I3 is 'available', would that not be a better option. Or maybe another model? I don't h

Re: Are these printed parts ok - 11 years ago

Hi All. Thank you for the replies. I have not actually purchased the kit yet. I was just checkling to see if this would be okay to buy. So do you guys think that this a good kit to start with? So, from what you can see, there are just the two RP pulleys missing to complete the printed parts of the kit? I don't have any build instructions for this specific variation of the kit, but I am sure I s

Are these printed parts ok - 11 years ago

Hi all. I am busy planning the build of my first 3D printer. A seller has offered me the attached set of printed parts for a Prusa. I see that some of the parts look a lot different to the other kits I have seen. Would this kit be okay to start off with, or should I look at something else? TIA Darryn

Hi all. I am busy getting together my list of supplies to build a Prusa I2 printer. I have decided to source the parts myself and I have a few questions: M8 Threaded Rod: Is there a particular pitch that it needs to be? Is there any specific materical it should be made from? I have been given the option of galvinised ready bar from a supplier. Would this be the correct threaded rod? M8 washe
