Re: Bigger 3d delta printer size - 8 years ago
If you balance the total weight with a counterweight or CF reel, I don't see the need to "fly" the extruder except for clearance about the effector itself. Werner Berry offers a dual extruder effector using his Nema 11 gear motor extruders. He uses a lead counterweight for his delta and hides the weight inside a sheetmetal riser cover. My enclosure design doesn't provide for concealment so thaby simspeed - Delta Machines
Re: Bigger 3d delta printer size - 8 years ago
Quotehercek I'm playing with a design which would use steel cables too. In my case, I would like to achieve at least 7g accelerations with about 0.05 mm dynamic precision while being able to go without bowden. Which is rather hard since the extruder stepper on platform makes the moving part much heavier. Good luck with yours. Thanks Hereck...I'm going to try both extruder approaches.

Re: Bigger 3d delta printer size - 8 years ago
Core XY provides for both XY steppers to be fixed where neither axis carries a stepper in the motion...right? Therefore the acceleration in both would be the same, would they not?by simspeed - Delta Machines
Re: Bigger 3d delta printer size - 8 years ago
I considered these issues in the design of my 1500mm vertical riser enclosed delta. I chose not to use belts and instead went with stainless steel syncromesh cables and matching pitch 15 tooth pulleys. The cables are smaller in diameter, lighter, and said to hold tension presets well. My design recessed the cables into the riser which allows placement of the carriages much closer to the verticalby simspeed - Delta Machines
Re: Alternative to T-Slot wheels? - 8 years ago
That's an interesting approach Rick... How much mileage do you have on your setup? How smooth is the movement? And..how long do you project the nylon will last?by simspeed - Extruded Aluminum Frames

Re: 1mx1m hot plate? - 8 years ago
The bed was made from 8020 aluminum extrusions locked together for a 23 X 30 bed size. The attached picture shows how I looped the nichrome and PTFE tubing through the extrusions to make a closed circuit. The PTFE acted as an insulator for the nichrome. That bed uses 110v mains power, draws about 12amps and heats to 110c. Max temp on the PTFE is about 175c.by simspeed - Mechanics
Re: 1mx1m hot plate? - 8 years ago
Hi rowow...thanks for contributing to my idea. Let me say I'm not trying to be argumentative toward other points of view, I'm just responding as best as I can to why I like the idea of using hot water (fluid) for my application. Your point that the heat capacity of water is very high is well taken. Water or a combination of water/glycol as described, may well not be the best fluid for this apby simspeed - Mechanics
Re: 1mx1m hot plate? - 8 years ago
Thanks DD...good info; thanks for your input. Just for clarification, the Stratasys ABS printer I had occasion to use, doesn't heat the bed; just the chamber. The bed plates are sacrificial ABS, but they appear to last well in normal use. I have several options for the bed surface, the Lexan itself is the first choice, but others are available. PVC sheet as used for shower pans is one option tby simspeed - Mechanics
Re: 1mx1m hot plate? - 8 years ago
My last post seems to never have appeared so I'll give it another try. I have researched and now seriously considering using a hot water recirculating system to heat the bed and enclosed chamber of a large delta I'm building. The bed itself is a 590mm dia. X 18mm thick three layer Lexan sandwich, where the middle layer is hollow to house plastic tubing for the circulating water. The system isby simspeed - Mechanics

Re: New Delta Printer - Look Ma, no rails! - 8 years ago
I have no objection to posting your project here Linkreincarnate (of course its not my thread to decide)...but I think you would better serve yourself and the community to create a thread of your own so that interest in your ideas and achievements would be easier for others to find and comment on in the future.

Re: GCodePrintr App - 8 years ago
Thanks for the detailed explanation Mathias. I have a question or two about the network print and web control. If smoothie has been configured for network access as described HERE, and has the ability to accept file streaming via the Telnet port from Ponterface to run console commands and g-code, can your app work similarly via a home WiFi network? If so, would that allow your app to stream thby simspeed - General

Hi Mathias...thanks for your response. I received your email as well and appreciate you looking into the PC version. I looked at your google group earlier, I'll join for more info and updates.

GCodePrintr App - 8 years ago
I've read the history of GCode Simulator app posts here on RepRap . The last one was some time ago, so I'm asking today is anyone here using this app on an Android tablet to control your printer? I downloaded the app to a quad core 8" Android tablet I have and set it up to receive gcode files from the slicer software on my home wifi networked PC.

Re: Printing on ABS Sheet - 9 years ago
I had a few ABS parts printed on a Stratasy printer. I was surprised to see the removable print beds are molded ABS sheet that are quick changeable. I looked at several used plate laying around to see that the parts separate rather well. The guy told me he prints a raft usually but occasionaly the bed is ruined. He pays $5 each for spares that Stratasy provides. It may be worth a try given tby simspeed - General

Re: Are direct drive extruders any good? - 9 years ago
I decided to give this one a try. Will need two but only ordered one to test. I broke it down when it arrived and the opposing gear filament drive looks solid and well made. The housing is well made too. Runs off a geared Nema 17. BondTechby simspeed - Reprappers

Re: Heavy Duty 3D Printer Build - 9 years ago
Since you have access to Solidworks, I'd draw the entire machine and all component parts to scale using mfg. cad drawings; or recreate .pdf dimensional drawings manually to you SW component part drawings. Building the machine digitally in 3D to exact scale, will help to identify potential issues that you can resolve before committing time and expense to machined parts. Good luck with your projeby simspeed - Reprappers
Re: Fired up heat bed - 9 years ago
The design doesn't lent itself well to a full enclosure. I do have a way in mind, but doubt I'll try to implement it for this machine. I've drafted plans for an altogether different type of machine that will get a full case enclosure with a lifting lid and double swing open doors. I really love working with the v-slot aluminum extrusions. Doors with magnetic latching, like I've used on the endby simspeed - General
Re: Filament Storage Practices? - 9 years ago
Here's how I rigged the filament spool feeders for my stainless Cartesian build. Air tight 2 gallon buckets from the big box home hardware store for the containers. The galvanized pipe stands have 1 1/2" ABS plumbing fittings screwed to the top of the pipes that seal up against the bucket lids. The fittings project about 2" into the bucket and the filament spools center on those. The filameby simspeed - General
Re: Fired up heat bed - 9 years ago
My design turned out very similar to the 3DP Unlimited large format printer. The XYZ movement is all in the gantry carriage with the bed fixed to the stainless cart I bought for the project. I dropped my extrusion parts off for machining today and looked at the finished bearing blocks as they came off the Stratasys printer. Man the detail from that printer is perfect and the parts fit perfecby simspeed - General

Re: Fired up heat bed - 9 years ago
Hi SydneyD... Thanks for your comments and questions. I'm planning to lay glass from an oven door on top of the aluminum bed for starters. You can see it in the photos above. Since building and testing the bed shown, I've put it aside while I work to complete the rest of the printer. This is my first build so I'm taking it pretty slow to be as sure as I can that the motion drives are designedby simspeed - General
