Duet and 500c Dyzend thermister - 9 years ago
Hey Chris or David, Has or can the firmware handle the Dyze Design Dyzend 500c thermistor they are using? They have published firmware configs for Marlin, Repetier and Smoothie. I know I could just buy a E3Dv6 and get on with it but something has got me intrigued with the Dyzend..... nearly hit buy twice in three days Cheers Philby aussiephil - Duet
Re: Frame integrity: Hexagon vs. delta vs Y-style construction - 9 years ago
I'll start some comments with a follow on from GroupB..... I personally think the Hex frame is potentially less rigid when built with the same items due to the additional joints involved in the hexagon shape. Add to that the lack of metal corners for a hexagon and your in questionable territory. So why did I go that way, well a hexagon is far easier to enclose with panels and if you make those paby aussiephil - Delta Machines

Re: First build - large Hex framed Delta - 3DR Mega style - 9 years ago
Progress is somewhat slowed by parts not yet arrived from China, though steppersonline got the nema23's here pretty quick so whipped up a mounting plate for them. The plate is designed to mount to the planned flat base plate that will be on top of the bottom extrusion set and underneath the printbed area. The 23's are 0.9 degree units and were not expensive so if no good then they can be used forby aussiephil - Delta Machines
Re: Bed size calc based on Arm length - 9 years ago
Thanks PRZ, That is helpful and actually quite awesome, sadly driving OpenScad is something I haven't worked out. I'll model the base dimensions to get 480mm circular clearance for the effector to all towers with a 500mm circular build plate. Cheers and Thanks Philby aussiephil - Delta Machines

Re: Bed size calc based on Arm length - 9 years ago
Quotedc42 Here is a simple approximation. If the arms are vertical when the head is as close as it can get to a tower, then cos(angle_at_max_distance) = print_diameter/arm_length. Putting in your figures of 500 and 520mm gives the angle as 16 degrees. So for you to get 500mm with not less than 20 degrees angle, the arms would have to go well past the vertical when the head is close to a tower. Soby aussiephil - Delta Machines
Bed size calc based on Arm length - 9 years ago
Help...... I'm trying to determine the bed size and hence the base measurements for my new Delta based on the actual arm length and effector sizing. I think I have it worked out but the printable area has turned out larger than I expected. Arm Length: 520mm Delta Effector Offset: 45mm Delta Carriage Offset: 33mm. Total available smooth rod travel will be around 1400mm (1.4M) so build height wiby aussiephil - Delta Machines

Thanks PRZ, hadn't seen the dual line setup before and it seems to be logical and sensible....... I wonder if making it one run of spectre line looped at one end but still parallel to each arm and dual springs would allow for tension variation on each arm to naturally equalise? Easy for a couple holes to be added to each side of my design though so thanks for pointing out the dual line configuraby aussiephil - Delta Machines

First print of the two part effector design has been done and everything is a nice snug fit, the inner ring is basic to check for fit and will be customised for the E3Dv6 mount and cooling ducting to allow for externally ducted air to cool the hotend. the two pieces apart and together with one M4 machine screw to check it can be screwed down,by aussiephil - Delta Machines

Re: First build - large Hex framed Delta - 3DR Mega style - 9 years ago
Despite have Traxxas rod ends on order I've decided in the last few days to head down the ball/socket set up for the effector/rods/carriage. Not magnetic but using spring/tension retention. I've read people having big issues getting them connected up but they seem to work well and give full movement.

PRZ, thank you, more reading and thinking material. I take the point about the counter weights. The reverse thought then as this.... The counter weighting is essentially in the vertical direction whilst we have increased the total mass iT actually becomes easier to move back and forward. The see saw analogy comes to mind, with equal weight on each end it requires small force to rock it. Take theby aussiephil - Delta Machines

Re: First build - large Hex framed Delta - 3DR Mega style - 9 years ago
Quotenebbian Flying extruders are excellent, especially if you want quality prints. The extruder itself doesn't really move when the effector does, it just sort of stays in the middle and tilts. It gives you the benefit of a short bowden cable, without the moving mass of an effector-mounted extruder. About the only downside is that they look a bit weird. Another option is the flex3drive, butby aussiephil - Delta Machines

Re: First build - large Hex framed Delta - 3DR Mega style - 9 years ago
QuotePRZ Plastic corners cannot give you bending stiffness, but if you stabilize the printer either by bolting panels or making a cross-bracing, they will be sufficient. The hexagon design is quite practical for that. I am for panels because I prefer enclosed printers, especially if you print ABS. Also, heavy wood panels dampen vibrations and noise.

Re: First build - large Hex framed Delta - 3DR Mega style - 9 years ago
Thanks for the quick response... Quotedc42 That's going to be a nice machine! A few suggestions: 1. Do not use printed corners, they are not rigid enough for a large printer. Finding metal corners for 120 degree joints is impossible in Aus and I haven't seen them anywhere honestly, I think i've engineered the printed versions with more than enough, photos to follow in separate post.

Firstly as this is my first post on RepRap a big hello. I have read a lot of posts researching Delta style printers with the aim of building my own. I bought a Flashforge Creator Pro in Jan 2015 and have around 2800 print hours and over 50Kgs using exclusively ABS. I can print dimensionally accurate parts so will be using this to print parts I need for the Delta and hence this post. Delta's looby aussiephil - Delta Machines
