Bear with me, its been a while since I've used Marlin. To control the printer via USB use I tried to setup a profile on cura for my Delta a few days, but despite setting all the parameters it keeps reverting to a rectangular bed. Superslicer works perfectly for my setup so im not changing anything. If it says driver error, it has to do with the settings of the driver. Check your microsteppingby lohiaprateek - Delta Machines
My steppers are barely warm to the touch. I'm using fairly low amperage on the motors without any skipped steps, also I've got those anti vibration dampers on them so the motors dont directly touch the PLA printed motor mounts.by lohiaprateek - Delta Machines
Due to the multiple covid lockdowns here in India, and the free time I had. I started to build a new "parts bin" delta printer. I've been printing since 2012 when I bought the Ultimaker Original and later designed and built a small delta which is my work horse. I had collected a lot of parts over the years and decided to build another slightly larger delta printer. Barring the Extrusions, the belby lohiaprateek - Delta Machines
Quoteleadinglights Although I do have access to machining facilities I did not need them for making the rods. Try using your ball nose milling cutter to cut a recess in the end of a delrin rod then file to fit. The most important thing is to get the length ball to ball the same on every one. It is also not usually necessary to have angled balls - see DC42s smart effector where all of the balls arby lohiaprateek - Delta Machines
Quoteleadinglights If you are on a really tight budget it is not too expensive to make your own. Magnets and steel balls are quite inexpensive and all you need to make are the bits to hold them all together. make the cups out of Delrin, Nylon or bronze - DO NOT MAKE THE CUPS OUT OF STEEL - that way lies only a deeper understanding of magnetic circuits and that what is obvious really aint so.

Quotedc42 I think you will find that the cost of 12 of the smallest/cheapest of those joints exceeds the cost of a set of 6 rods form Haydn. Although you might save a little on carriage. You can buy Haydn's rods in one particular length from the UK at . I don't know whether the shipping would cost any less than from Haydn direct. So an aliexpress seller is selling the 10mm balls with an m3 threby lohiaprateek - Delta Machines
I have been printing my own rod ends for a while and started to look at some alternates which are more professionally machined. There are the rods from Haydn which everyone loves, but I'm on a budget and shipping to India makes it slightly out of my reach. As an alternate to Haydn's Rod, has any one tried using something like this or they are essentially the same thing. Adding a little bit ofby lohiaprateek - Delta Machines
I figured as the centre top section is kind of pointless, and would have added to the weight making it top heavy.by lohiaprateek - Delta Machines
So I have been using something simillar for a while. Although I got my frame laser cut in steel for around USD 7.34 which included the price of the steel. Attaching the photo of the printerby lohiaprateek - Delta Machines
So as per the Delta Geometry Page the minimum recommended is 20 deg. I use trigonometry to figure out arm length. cos(θ) = Adjacent / Hypotenuse is the basic formula. Here is how I go about it (Printable Radius + Offset of carriage to Print Bed - Offset of rod centre and hotend centre)/.9 (.9 is cos(25) I use a minimum angle of 25 as I use printed rod end). You may want to adjust the minimumby lohiaprateek - Delta Machines
Ah well, somehow my DIY delta with lower acceleration settings and same speed settings ends up completing prints 1/4 faster than my ultimaker . Other than the obvious printer style difference, the profiles are identical. Something that takes 1 hour on my ultimaker with 60mm print speeds and 100mm travel gets completed in 40 on the delta, even though the delta is configured with 1000mm of acceleraby lohiaprateek - Delta Machines
I guess changing the motors to a low inductance motor helped. I have been using them with TMC2100 and I guess they disagreed with the no name Chinese motors. Mine prints fine with LCD and segments as high as 160 anything higher it starts to stutter, I'm sure using no LCD I could bump it up further, but I'm happy with the result. Attaching a photo of something I printed yesterday. Cheers guys.by lohiaprateek - Delta Machines
I switched to Marlin 1.1.7 and it seems to be perfect and as expected, I realized I had some no-name Chinese nema 17 motors which were also the source of the stuttering, my old Ultimaker motors were smooth. New motors are in the post and should be here soon.by lohiaprateek - Delta Machines
So my problem is with 120-130 segments it prints fine without any issue of stuttering, but with lower segments the apparent speed of the print is increased drastically. I was using the cheap MKS board with smoothieware and the it printed fine with 60mm speeds and 120mm travel speeds. Shifting to the 8 bit board with 120 segments with the same print profile makes it impossible for the extruder tby lohiaprateek - Delta Machines
Sure, the problem the speed settings I was using with smoothie have to be halved when changing to Marlin with 120 segments, or else the printer is just all over the place and my extruder cant keep up. Is this normal?by lohiaprateek - Delta Machines
So I've been experimenting and trying to build my own delta for a few months now. And I needed some help with Marlin. I've reduced the Delta Segments per Second to 120 from the default 200, and it prints fine and I have no issues with the Delta stuttering, but the downside is that the printer is now printing much faster than what it was printing with 200 segments. Is this something that is normalby lohiaprateek - Delta Machines
