Z-Axis Limit Switch (Cura inverted Z-Axis) - 11 years ago
Hi, I have my Z-Axis endstop set as a maximum (being the top of the printer) but Cura has Z0 be the top of the printer. Right now Z0 makes the build plate go to the bottom. I would like to either: Invert the Z-Axis on Cura (A setting which I cannot seem to find) or change the Z-Axis limit switch from being a maximum to a minimum limit (making Z150 be the bottom of the printer.) Can anybody help wby Evmanw - General
Re: Power Supply Amperage Help! - 11 years ago
Ok, that makes sense. Now, I purchased a heater and I just realized that it runs at 10.3V. Is there any way while still using the same 22A 12V power supply from MakerGeeks (link above) to be able to run this heater?by Evmanw - RAMPS Electronics

Quotecdru You don't decide how much power goes in. Electronics, whether they are a micro controller, stepper motor, or heated bed, draw current...the current isn't pushed to it. You just need to hook up the wires, usually 2 or 3 are sufficient to each connector. The ATX specification says that the yellow wires are +12V and the black wires are ground. Those are the only two that you need asideby Evmanw - RAMPS Electronics
Re: Power Supply Amperage Help! - 11 years ago
So if I have a power supply with these specifications, how do I figure out the total amperage that goes into each side of the RAMPS board? DC Output Specifications: +3.3V, 22A +5V, 30A +12V, 22A -12V, 0.8A +5VSB, 3Aby Evmanw - RAMPS Electronics

WOW! And it sounds pretty good too! How much plastic did it use?by Evmanw - General
Power Supply Amperage Help! - 11 years ago
I am designing a printer and I have purchased a RAMPS kit and four stepper motors. Each stepper motors is 1.5 Amps I will also need a heated bed plate (plugged into D8) (This is all going to run at 12V by the way) Now for my questions: Can my heated bed plate be more than 11A if I buy a power supply capable of giving that much power? Is anything else using power from that half of the power termiby Evmanw - RAMPS Electronics

QuoteUkIan Interesting, I guess you heat it to the lowest temp it flows and only heat it to stage five at the nozzle? For ramps, they pretty much all come assembled. The Stepper drivers slot in sockets, then all the wires for thing plug onto various pins. The price didn't look awful, but could be cheaper I think. Are you in the states? There are a surprising number of English and European peoplby Evmanw - General

QuoteUkIan And sorry to hijack your chocolate thread, it's all useful info haha its fine! This is the kind of stuff that I am trying to learn about right now!by Evmanw - General
Re: In over my head with chocolate printer electronics! - 11 years ago
QuoteUkIan Ramps with 4998 drivers Imo. Even if you could find a use for three extruders, you'll find it hard to drive them all with the available software. Question for each of you Is chocolate hard to melt? I mean does it have a narrow band ewen Molton and burnt? Does anything support the 8825's 32x Microsteps? They seem price wise not far off the 4998 I am considering using a RAMPS pre-asby Evmanw - General
In over my head with chocolate printer electronics! - 11 years ago
Hey, I am currently designing and building a chocolate 3D printer, but I am having trouble choosing electronics because there are so many options. Here are my requirements: • I need 4 stepper motors, • 3 (maybe 4) end-stops, • 1 or 2 heater (I am not sure yet), although this does NOT change the number of stepper motors. • 2 (or 3) fans • 2 (maybe 3 or 4) thermistorsby Evmanw - General
