Quoteo_lampe I couldn't identify microstepping jumpers, are there any or do you use FW configurable drivers? There are micro stepping jumpers, just like the RAMPS 1.4, only with some additions, so it becomes possible to select the SPI signals for the TMC2130 drivers. Here are illustrations of how to use the jumpers:by MrAlvin - RAMPS Electronics
That sounds very correct. The math is like this you need 360W + something to cover heat losses. So lets say 450W (this allows as low as 75-80% efficiency). Then you get 110V (and perhaps it goes a bit lower at times - so lets say 100V). How many amps does a 450W load use at 100V? W/V = A, so 450W / 100V = 4.5A And thus a 5A to 6.3A fuse will allow the power supply to operate even under non-by MrAlvin - RAMPS Electronics
Hi isralgs, what kind of expansion board do you have?by MrAlvin - RAMPS Electronics
In the hopes of keeping a low entry price point, I have tried to limit additions to the board. And kept it as much as possible as add-on options. But I have tried to include connectors for typical add-on options. My main design goal has been to be able to easily use TMC2130 drivers boards. My second design goal has been to be able to easily switch between using an Arduino Mega or an Arduinoby MrAlvin - RAMPS Electronics

QuoteDust "an easy path to run heat-bed and/or steppers at 24V volts. " Nothing stopping that on current ramps, the issue is the voltage regulator on the mega... Ah yes, there is a need to add a 24->8V regulator, before Vin, but then the current board will indeed work with 24V.by MrAlvin - RAMPS Electronics
For some time I have been tinkering with designs for a board, and I have already gotten to iteration 3. But before I get serious about making a design ready for (open source) publication, I thought it might be a good idea to get some input about wishes and experiences, especially to see if there is anything I have overlooked. So I really appreciate your comments and input. In the process of trby MrAlvin - RAMPS Electronics
The RAMPS 1.4 board has been used very successfully for many years now, but it seems to me that it might be time for an upgrade to the design. Will it be okay to ask in this forum location, about what people most want from a upgraded design of the RAMPS board? Among my own wishes are: - to make it much easier to use TMC2130 drivers. Like I would want it to be as simple as moving some jumperby MrAlvin - RAMPS Electronics

Gerber files are a set of files, produced using you PCB Cad software (in your case Eagle). Typically you produce one gerber file for each layer in the process, For a double sided pcb, these would typically be: copper top and bottom, silkscreen top and bottom, solder stop mask (the "green" color) top and bottom and a drill file, in all seven files. One process layer can consist of one or more "lby MrAlvin - RAMPS Electronics

Hi Tom, thank you for your donation. Funding is going quite slow, but we are getting there. I agree with you, that MetalicaRap is a great project. It is however a rather heavy engineering job to iron out all the details of the technology. Only very few people - that like open source - are however able to take in the level of detail needed to actually "engineer out" a project like MetalicaRapby MrAlvin - MetalicaRap
