I want to build my own printer. I started looking for a stepper motor (it should have more than 4.5KG.m torque) but then i was a little confused. For a 3d printer we want a strong motor but a fast motor too. So, how do i know how fast is a motor? Yes, i'm familiar with the torque vs speed graph. There isn't a way of getting a little more speed with a motor and lose some torque? For example, i foby TheDeadLives - Stepper Motors, Servo Motors, DC Motors
Yeah, that was my idea. I wanted to see some schematics, make one board and see what i could make better. Furthermore, i would try to help a little in the code. Releasing it would be a great idea.by TheDeadLives - Controllers

QuoteDust There is marlin electronics... It has been mentioned how this how it was going to confuse everyone. I don’t know if it ever got released.. As you can see version is V0.1 So far its vapour ware. I suspect your looking at this as you spotted the SPI steppers... (not yet normal for a reprap) Take a look at is also a SPI stepper controller ie TMC2660 Stepper Driver and 4amp... aby TheDeadLives - Controllers
Yes, i know that Marlin is a software. But, if you check this page: you will see that exists marlin electronics. If you go to github, and search by Marlin II there is a photo of the elctronics, the one that i posted: After all, there is or not a marlin electronic (in the image the pcb as the name marlin)? And the image is in the github of the creator of marlin Graefulby TheDeadLives - Controllers
Grateful for your reply. My only problem now is if L6470 will work, since it uses SPIby TheDeadLives - Controllers
Does anyone know where i can get the marlin electronics? I already searched online, in github, but i'm not able to find the marlin electronic that is described in reprap comparison of electronics (http://reprap.org/wiki/Comparison_of_Electronics) Just can find this picture: If someone could help i would be gratefulby TheDeadLives - Controllers
QuoteTraumflug VDX is right. Also note that 2.8 A stepper drivers don't neccessarily need a 3 A stepper driver. They work with 1 A drivers just fine. Torque is reduced accordingly, of course, but motors specified for 2.8 A have likely much more torque than you need. In my case, i would be needing the 2.8A stepper drivers (10N.m). VDX, did you had to modify anything in the code? Gratefulby TheDeadLives - Controllers
Hi all, I'm interested in making a 3d printer. I started looking for stepper drivers and decide to choose the drv8825. Now i started to look for stepper motors and all that i find in ebay are rated to 2.8A per phase. My question is, there is any good stepper motor 3A driver that can work with ramps? What do you think of ? As anyone tried it? Gratefulby TheDeadLives - Controllers
Quotethe_digital_dentist Putting the electronics under the printbed sounds like a good way to keep the printer small, but you might want to reconsider. You are making a pretty big printbed, so I assume you are going to want to make big prints. If you try to make big prints with ABS and you don't enclose the printer your big prints are going to delaminate even as they are printing. I suggest thby TheDeadLives - Mechanics
QuoteDamonh I've read this thread. Currently I am building the tantillus t-slot variation. I want to go to a 200mm x 200mm build area. I real new at this so bear with me. I've been trying to figure out the lengths to cut the I have 2000mm of extruded aluminum and calculate I can get 8x 250mm lengths for the horizontal sections.

Quotejbernardis I started out with a prusa that had a 200x200 bed. I've since rebuilt it to a different design that also has a 200x200 bed, and I have designed and built a second printer that has, you guessed it, a 200x200 bed. I think the 200x200 size just came about because of the size of the frame that can be built without moving up to sturdier parts - like 10mm bars and such. It has evolveby TheDeadLives - Mechanics
I'm trying to figure why there are printers so big (like makerbot) with 200x200 heatbed and then some, like prusa, that are smaller. I'm asking this because i want to build a 3d printer, but i can't really understand the differences. Is there any rule for heatbed vs 3d printer size? Gratefulby TheDeadLives - Mechanics
Hi all, I'm new to the forum. I'mt thinking about construct my own 3d printer. I'm searching for some information and i come across with the pulleys and belts. Tried to see what are the differences, read some posts in reprap's wikipedia but i' not able to find an answer to my questions. The question is, what are the differences between the pulleys (gt2, 2gt, mxl, htd, fht, xl)? Which one is betby TheDeadLives - Mechanics
