I see there is a new Ingentis google group and there seems to be a lot of concern of the bed dropping at an uncontrolled rate when the motors disengage. I would post there but being signed into Google is not good enough and Google tries to force a G- page on you so I will post it here and hope it makes it there. A nice simple way of slowing down the movement is with a fluid filled cavity. Theseby Sublime - Tantillus
If you only have $350 to spend you do not get to make choices. You will only be able to build/buy the cheapest of the cheap FFF printers like a printrbot simple or similar. For a Resin printer be sure to add a zero to the end of your budget.by Sublime - General

Yes the other designs are more complicated to build but easier to get square. The machines that have a large moving mass like the bed moving in X/Y or like the makerbot that has the X motor on the Y axis as well as the extruder motors all have the issue of limited acceleration and speed due to the extra weight. This speed limit obviously limits the max speed you can print which is not that big ofby Sublime - Mechanics

QuoteA2 Neat linear drive-guide integration. QuoteSublime But with this system the belt can stretch between the roller and the fixed points at the ends which kind of defeats the purpose of a rack and pinion belt system.

Although I am all for belt Z axis I do not think that would be the best for Z since you would have the weight of the motors on the Z axis which would mean most of the motors holding torque would be used up just holding them up. On a slight side note, the commercial rack and pinion belt systems have teeth that the belt sits in on the track that prevent the belt from stretching anywhere except betby Sublime - Mechanics

Quotenaxem42 Given a 20 tooth pulley, the belt will move 20mm per revolution (I think) because each tooth is 1mm. Most RepRap suppliers sell 2mm pitch GT2 blets and pulleys and I have some that are 3mm so it would move 40-60mm per revolution with those. Also note that the larger the pulley you use the less backlash you will get because it gets averaged over the teeth.by Sublime - Tantillus

The F code is mm/m because that is the standard for gcodes used for milling etc. But with 3D printing we need much higher speeds so we talk in mm/s and set things in the slicers at mm/s to avoid huge numbers. I print at 55mm/s and travel at 150mm/s and if those were in mm/m it would be 3300mm/m and 9000mm/m which would be strange to input into the slicer.by Sublime - Firmware - mainstream and related support
Quotesirphilip Hey Sublime, thanks for the fast reply. My printer has leadscrews on X, Y, and Z - all with the same stepper motors. So I believe all the settings should be the same for each dimension, please correct me if I am wrong however. This is why I think I need a full rotation to go 1mm for X, Y and Z. Do you know why adjusting DEFAULT_MAX_FEEDRATE has no effect on the default feedrate?by Sublime - Firmware - mainstream and related support
The unit per step is 1mm of axis movement, not 1 revolution. So your 3200steps per mm @ 50mm/s would be trying to take 16000 steps per second which will never work on X and Y. On Z it is correct with the 1mm pitch but Z will only be able to move at 2-3mm/s. Also the F command is mm/m and the slicing software and firmware are mm/sby Sublime - Firmware - mainstream and related support

Ingentis is geared down because he is using something like a 36 tooth pulley for the main belt as well so it needed to have the reduction to get a decent resolution. His gearing now allows for a really nice layer interval with something like 0.01mm per step. For Tantillus's cable Z axis it is a spool directly attached to the motor and has a limited layer interval based on the printed spools finalby Sublime - Tantillus

Quotejkoljo whereas with especially bowden fed systems the 1.75 mm stuff is a clear winner. No way. Even E3D says 80% of the problems are with 1.75 and Bowden. It is by far the loser with a Bowden. I only run Bowden systems and 3mm is great. I can retract and unretract 5mm at 47mm/s with acceleration of 10,000mm/s^2 and never have to worry about filament buckling or breaking.by Sublime - General
