Red and Silver, East TN Build

[howe001 (Glenn Howe)]

Starting my log off with screen prints from my slicer. My first two parts printed without issues. I’m happy with them. I’m sure they could be better, but they fit the EMT conduit and look pretty good.

Please feel free to murder my settings. I’m always happy to learn something new. Let me know if I’m overdoing the information.

Printer: Anycubic I3 Mega S
Slicer: Prusa
Filament: 3D Fuel (Fire-engine Red, Simply Silver)
Router: Bosch Colt
Controller: Rambo 1.4
Work Area: 24x36
EMT: 3/4 23.5mm (Lowes)

[turbinbjorn]

Hey mate, welcome! Honestly, looking through the images is quite a hassle! What about getting a text output and showing it instead? I think it’s possible somehow, don’t remember the details.

Anyways, I think the speed recommandations are a little lower than what you are running - but that’s differing wildly depending on the printer and comsic fluctuations… if you are safe running those speeds, no worries. If you want to be certain, you can bring them down to around 30mms. And I don’t know if 4 perimitres are necessary, 3 might be enough.

[howe001 (Glenn Howe)]

@turbinbjorn - Thanks for the response. I’ll look into getting a dump of my settings from Prusa Slicer. So far the print jobs are coming out pretty nice (I suppose, I’ve only been at this 3d stuff for about 10 months, so still pretty new at it). Lamination looks good, the only complaint is the “hairy” prints when the hot end crosses over a void. Again, I’ll tackle the output settings to text only. I’ll post those when I figure that out.

Thanks again.

[turbinbjorn]

I’ve scratched my head many times over the hairy strings! I’ve read that it’s a difficult balance, between retraction and flow rate. It’s better to brush (heat) off the strings, that having sub-par print quality.

[jeffeb3]

If you can get the stringing really fine, you can just go over it quickly with a lighter. They disappear quickly.

If you retract too often, you can get in a situation where the same piece of plastic is going back and forth through the extruder and it will get damaged or warmed up.

[howe001 (Glenn Howe)]

wow… this is taking a long time

[howe001 (Glenn Howe)]

[howe001 (Glenn Howe)]

almost there…

[howe001 (Glenn Howe)]

Is this the only line in config.h (509D) to be change in order to add a single extruder/part fan/heatbed?

// This defines the number of extruders
// :[0, 1, 2, 3, 4, 5, 6, 7, 8]
#define EXTRUDERS 0

// TO

define EXTRUDERS 1

???

[jeffeb3]

No. The temperature sensor needs to be set. The steps per mm needs to be set. Do you have an skr? The rambo doesn’t have 6 drivers, so you would have to switch to serial wiring and firmware.

[jeffeb3]

There are MP3DP versions in MarlinBuilder releases. They are not dual endstops.

[howe001 (Glenn Howe)]

No, I have the Rambo 1.4 . Guess I misunderstood the diagram. My mistake. I guess in serial mode for the steppers, the “dual home” would not work if wired in that configuration and what is the downside to doing this with regard to overheating or stress on the rambo board or stepper motors?

Thanks

[howe001 (Glenn Howe)]

I see you answered my question about dual endstops before I posted my question, but what about stress on the board/motors using the serial configuration.

[jeffeb3]

There is no stress on the motors or drivers. It is counterintuitive. Series wiring is a good solution.

[howe001 (Glenn Howe)]

Ok, another stupid question from an old guy. So initially I was going to use the dual endstops and I wanted to be able to use it as a 3d printer as well as a cnc router (because I did not understand I was out of drivers). Now it clicked in my mind, I’ve flashed this Rambo 1.4 board with 510D (dual) and now I plan to use the serial stepper motor wiring. The question: So that means I need to reflash it with “non dual” firmware and turn on TEMP_SENSOR 0 11 in configuration.h?

Ok, one more question (which I don’t think is stupid, maybe it is), if I’m using the non-dual enstop firmware, can I still use limit switche(s) to home for z and x (realizing it all has to plug into the min-sig for X and Z which is one plug each now since I’ll be using the non-dual)? and if I can, can I or should I hook them up in series (per axis x and y - not Z obviously) so it opens the circuit on both sides of the axis or is that even necessary?

Thanks again.

[jeffeb3]

You should be much closer if you start with MP3DP_Rambo. Which is serial, and has an extruder defined (mk8, I think).

[howe001 (Glenn Howe)]

Bulk of printing done. Just need the tool holder, but the parts that make it zoom are done.
On to belts and wiring.

[howe001 (Glenn Howe)]

Yay me!

[jeffeb3]

Nice crown.

[howe001 (Glenn Howe)]

Ok, got it wired up and X and Y home work fine. Using the serial motor wiring as advised so I can use this MPCNC as a 3d printer also. I’m running the MP3DP firmware 510P.

My only issue left to deal with this: Z probe (as in I want to use a touch plate for bit changes and CNC work. So, using Z min (based on the board layout “Board” , but when I use cnc.js or repetier host and issue M119, Z shows trigger unless I short the signal and ground together and then it shows open. Also, if I clip wire to bit and touchplate , execute G28 Z , Z goes up about 5mm and stops. If I clip the clip to the touch plate (shorting them), then it issue G28 Z it begins its descent as expected and stops when I un-short the touchplate.

I tried #define Z_MIN_PROBE_ENDSTOP_INVERTING true this but did not work. Same results as above.
