Re: 3D cement printer - 11 years ago

I remember about the dutch tab and already talked to local guys if someone wants one , because I can't have it on my backyard(neighbors will not be happy) Also I talked to friend of mine who is an metal artist to make something fancy about the pipes. And finally ihave got an idea to make two in one: a hot tub inside a castle( or another kind of small fancy structure. ) the problem is its to heav

Re: 3D cement printer - 11 years ago

How are you supporting the interior portions of the turrets once they are placed? I don't' see any interior walls in the castle itself .-------- ¾ of the portion has support from the wall, and the last 1/4th hangs on its own. How did you handle the horizontal bridging in the rectangular windows? Is there some kind of metal or wood support there? –----- I just opened a website- www.totalkustom.c

Re: 3D cement printer - 11 years ago

It took a while but in the end the result is here. it was a bad idea to print separate parts of the castle. the parts are quite heavy and will need some effort to lift. Next project I will definitely print as a one solid object and will try to print nonstop. after I printed the castle based on the experience gained, I decided to completely redesign the printer. one of the problems that app

Re: marlin pulse width issue - 12 years ago

what I found: Alan Wood: We changed the firmware (Marlin) on phoenix drivers (Tosh based) to extend the step width, we detected this problem in the early days of testing the Tosh drivers. We don't get issues with loosing or missing steps, or speed of the axis, its the extrusion process itself that ultimately slows us down. In fact the new controllers and drivers we are exploring are even lower

marlin pulse width issue - 12 years ago

I'm digging for a month how to change a pulse width for marlin. So far what I have I can change a delay after each pulse in stepper.cpp in the Marlin Folder line 242. void step_wait(){ delayMicroseconds(5); but looks like it does not really help. I still have hissing , grinding sound, vibration e.t.c. here is my extruder's driver .I'm using AC80V or DC110V 7.2A driver The goal is to get

cpus ----- in about a week im going to print a large structure outside, so i can make a video tutorial how to build the printer.

Re: 3D cement printer - 12 years ago

I did not remove the rotor. The gunk are just graphite lubrication from the front stalled bearing. I replaced the bearing but due poor design can not ally the front and rear ends/covers with the stator, the rotor rubbing the stator. So I need a step motor, bigger, better, hight torque. And dont know how to calculate which is the best fit for my driver.

Re: 3D cement printer - 12 years ago

A2----- thank you for showing the program. It was helpful! I have some updates transforming from: CAD---->SLICER--->GCODE--->PRINTING was successfully DONE as you can see on the pics. I am using sli3er. It looks like Kisslicer cannot handle very large models or maybe I cannot make the right settings. arches looks pretty good too. the bad news is that I cannot finish the print be

Re: 3D cement printer - 12 years ago

The good news is that kisslicer works. The bad news is that for some unknown reason, all lines are broken up into short segments, .What I see in gcode: kisslicer"thinks" the lines/walls of the model are curved/bent or rotated and I cannot figure out why or how to fix it G1 X578.93 Y400.13 E1.8498 F4800 G1 X578.95 Y417.31 E2.0092 F571.6 G1 X578.89 Y451.61 E2.3275 G1 X578.9 Y467.15 E2.4717 G1 X57

looks great, lets print! .... plz STL !

Re: 3D cement printer - 12 years ago

QuoteA2 QuoteAndreyR I mean segments are short line that move point to point to make a circle Are you saying that you want the circle to be comprised of a series of chords, i.e. straight sections?-------it is already a series of chords around the circle.this is not a true circle. you can see it on your drawing., and its kind of visible on a large model . Would be better to have like more shor

Re: 3D cement printer - 12 years ago

Ok, I'll add the 90 degree corners back, and I'll add two arches.----------------------------only small corners, that inner-circle-wall looks great How much space do you want between the top of the arch and the top of the wall?------ about 80mm To be clear, segments are ribs between two adjacent walls?-----------no, between walls going to be just concrete or insulation. I mean segments are short

Re: 3D cement printer - 12 years ago

I spent about twelve hours trying to get Slicer/Kisslicer to work today, and have finally gotten good results. Everything looks very promising, and it appears that we’re on the right track. I'm going to print this model, but before printing, I would like to ask you to make some changes. Firstly, we need to increase number of the segments about 3- 5 times. Secondly, it looks like you made a small

Re: 3D cement printer - 12 years ago

Re: 3D cement printer - 12 years ago

A2- I think we need to start from this simple shape. Then if we are lucky and Kisslicer works okay, we can make a more complex model. Scire- Thank you, much appreciated. Please join, we are always open to new ideas and new members. A lot has been done, but even more is ahead.

Re: 3D cement printer - 12 years ago

oh man, you surprised me about the castle! I'd like to start with a round-barn-house. Can you help with a stl file? I will definitely experiment with KISSlicer, as jzatopa advised. I guess I need a stl, right? The thickness of the walls is 20 mm, and can you make the trim/door to be very simple? The thickness of the layers is 5mm, but i think it should be settings on KISSlicer. By the way, i reme

Re: 3D cement printer - 12 years ago

I can try.Can you design 20mm thikness and about 1000mm diameter?

Re: 3D cement printer - 12 years ago

What slicers have you tried so far? ----sli3er Is the limitation the inability to draw the walls to the thickness that you want------------------yes. problem is how to print a wall in one path. the thickness of the wall is about thickness of the filament. i have 20 mm nozzle diameter and 25 mm thickness of the wall ( you can see it on the video) Or is there something about plastic filament s

Re: 3D cement printer - 12 years ago

The first part of the experiment was a success. At this time, I have reached the phase where the 3D printer can print straight, even layers and be configured to print different shapes. The next step is to build a small castle that will be used as a children’s playhouse. This project will allow me to test printing walls other than straight walls. I need to test the printer’s ability to build leani

Although this topic is not for this forum, there's a lot of people here who are experienced with software and hardware, so I want to share my idea.

Now our smartphones have much more capability than computers 10 years ago. Towers were option

Re: 3D cement printer - 12 years ago

QuoteJamesNewton QuoteAndreyR QuoteJamesNewton But it looks like the DC motor works ok for you... why change? As you can hear in the video, the rotation speed/RPM varies because the cement mix is not the same consistency throughout the entire extrusion and that's the major source for the discrepancy in the layers' width. And as you can see, the extrusion speed need to be reduced on the corners.

Re: 3D cement printer - 12 years ago

QuoteA2 I'll design you a Dutch hot tub What is the wall thickness, and the actual layer height? That will help me design the Dutch hot tub so you don't have to compromise your slicing. How many person, or would you like the design to be near the size of the original? About 10 years ago I designed a Dutch tub after the original, but I modified the interior walls. The walls were curved to put n
