The fact that the printer came with a Duetwifi control board is the main reason I chose this model.by vhoward1122 - Delta Machines
I had used a pre-made profile for the Rostock Max v3 in S3D. I thought I had to change the build volume. It was set for circular and x and y was set to 197mm with an offset of 98.5 on each. So I changed the x and y to 275 and put 0 in the offset. Then I did a slice and tried to print it. It was printing off to the side. I asked about this in the Facebook SeeMeCNC printer users group and a guy resby vhoward1122 - Delta Machines
Hi. I recently bought this delts and assembled it. It prints nicely. I am having a problem getting Simplify 3D to put the model in the middle of the build plate though. Seemecnc has a guide for setting up S3D for the Rostock Max v3 and I followed that and just changed the build volume to fit the machine. When I slice a model, S3D shows it in the center of the build plate. Yet when I upload the fby vhoward1122 - Delta Machines
OK. So machines such as Prussa I3 that have a stepper for each axis is categorized under the cartesian section? Smoothieware.org is what I have been reading. Just trying to understand terminology. Not quite as easy when my whole experience 3d printing has been with Marlin firmware. That I understand, but a friend insisted I could do better with a smoothie board. And now I can't get a hold of him.by vhoward1122 - Smoothie
I have been reading a lot on smoothieware and have changed a few settings in the config file. In the documentation on the smoothie wiki, when going through the 3d printer section and come to a link to a cartesian section, that section is blank. Is the config file already optimized for the standard cartesian style printer? Also, the first few sections of the config file is a little confusing. Quoby vhoward1122 - Smoothie
It is the M5 threaded rod provided in the kit. That steps/mm is 4000. Everything is running correctly now.by vhoward1122 - Prusa i3 and variants
In my case, it was a flakey ramps board.by vhoward1122 - Prusa i3 and variants
I can check that. Folgertech is sending a replacement in any case.by vhoward1122 - Prusa i3 and variants
Thanks for the wiki link. Just did not want to damage the motor by putting wires in a random order.by vhoward1122 - Stepper Motors, Servo Motors, DC Motors
Hi, I bought a sc42sth47-1648a 1.8 degree 2 phase motor to use with a different extruder setup. When I received the motor, there are 4 wires sticking out of the motor with no connector at the end. I received no wiring diagram for the motor. The wire colors are black, blue, green and red. I looked into the opening they come out of and the red and green come from the right and the blue and black coby vhoward1122 - Stepper Motors, Servo Motors, DC Motors
All the jumpers were there. It did that on the original ramps board. Everything is fine with the new ramps board. But that sounds like what was going on.by vhoward1122 - Prusa i3 and variants
OK. Thanks. For some reason, I had it in my mind that they both had to do with filament.by vhoward1122 - Repetier
Hi, In Repetier Host in the manual control tab, there are two items under the control buttons for the axis'. One is feed rate and has a slider for adjustment and the other is flow rate and also has a slider for adjustment. What is feed rate? What is flow rate? It might help me to understand these so I know what they do and can make the appropriate adjustments. Thanks Vanceby vhoward1122 - Repetier
That's why I am collecting extra parts to build another larger 3d printer. My Folgertech Prussa I3 is just a learning journey for me. I too will be following this.by vhoward1122 - Prusa i3 and variants
I have a co-worker that is an electronics engineer. He might be willing to test the board and he might not. He's been giving me suggestions too and it was his idea to swap out the ramps boards. He was thinking it was a faulty motor also and also does not like the idea that both z axis motors are driven by the same stepper driver. Since I already had the other ramps board setting here, he said itby vhoward1122 - Prusa i3 and variants
I want to thank everyone who responded to help me. It was not a faulty motor or stepper driver. It was a faulty ramps 1.4 board. I happened to be collecting items for another project and have another ramps board along with more stepper drivers. I installed the other ramps board and made sure all the settings were correct. Did another test cube print. Let me say that the improvement is like day anby vhoward1122 - Prusa i3 and variants
Quoteitchytweed It is entirely possible that you have a bad motor. I have not been a fan of putting two steppers on one driver. When wired in parallel, the driver has to supply the sum current of both steppers. So, if the steppers are nameplated at 1.2 amps, the stepper has to deliver 2.4 amps to supply the demand providing the steppers are the same electrical construction. In series, the currentby vhoward1122 - Prusa i3 and variants
The couplers are not slipping. I switched the wires and the problem did not follow it. The left side goes up faster, but does not come down as fast. It is still over 6mm higher than the right when it finally comes home. So I am thinking that the left motor is defective? Or would the right motor be the defective one?by vhoward1122 - Prusa i3 and variants
OK. I will try swapping the wires.by vhoward1122 - Prusa i3 and variants
OK. So I checked the configuration.h file and the default max feedrate for the z axis was already set to 2. I did change the default max acceleration for the z axis to 2 from 5. I also had an idea that maybe I had a faulty stepper driver on the z axis so I swapped the stepper drivers with the extra extruder driver. The z axis motors no longer scream when I move them or when the printer moves thby vhoward1122 - Prusa i3 and variants
OK. I understand that the z axis is totally dead then and won't home? You will need to provide additional info for someone else to help. I am also new at this and learning. As I've learned, it helps to specify which controller boards you have, which stepper drivers you have, what firmware you are using and what software. Sounds to me though that you have a faulty stepper driver. But you might wanby vhoward1122 - Prusa i3 and variants
Did you click on the home buttons for the x, y and z axis? The motors won't move until they get homed so the machine knows it's limits.by vhoward1122 - Prusa i3 and variants
I won't get a chance to work on this tonight. Tomorrow it will have to be.by vhoward1122 - Prusa i3 and variants
This is the motor that Folgertech includes in their kit for the z and x axis and for the extruder. They sent a bigger motor for the y axis, but it is also 1.8 degree steps. Folgertech tells us to install 3 jumpers under each stepper driver, so I assume that means it's set for the 1/16 micro stepping. The firmware already is set for 4000 and the machine has the 5mm threaded rod for the z axis. Iby vhoward1122 - Prusa i3 and variants
I also did not change any values in the configuration.h file as the speed values for the z axis were already low. I did try going to the configurationadv.h file and uncommenting out the dual z axis define line to use the spare extruder stepper driver for the second z axis stepper motor. Set it at .350v the same as the regular z axis stepper driver was and tried it. That made the left motor twiceby vhoward1122 - Prusa i3 and variants
Well I increased the milliamps provided to the z axis stepper motors. Probably not enough. Folgertech specifies .350v for the x,z and extruder stepper motors and .550v for the y axis stepper motor. There are 2 z axis motors so you would think you would need to provide more amps for them to work. I increased the z axis stepper driver milivolts to .550v and the problem persists. It's not as loud, bby vhoward1122 - Prusa i3 and variants
It is the marlin firmware. Arduino 2560 mega, ramps 1.4 and a4988 stepper motor drivers. I saw those lines and wasn't sure, so did not mess with them. I'll try that. I'll look at the current settings again. Thanks.by vhoward1122 - Prusa i3 and variants
I looked through the config.h file and did not see what I need to change.by vhoward1122 - Prusa i3 and variants
I printed my first test print. Besides needing to tweak the temps and extruder feed rate, I found that when the printer wants to raise the nozzle for the next layer, it makes a cavitating sound like the driver is trying to drive the 2 z axis motors too fast. This causes the carrier to go up unevenly. the left motor does not move the carrier up as much as the right motor does.. I am thinking if Iby vhoward1122 - Prusa i3 and variants
