The whole solution is also pursuing an user friendly function. This way the tube length is fixed and we minimize the problems caused by gaps, and the extrusion process doesn’t cause lowering displacements. The extruder’s motion is in phase with the hotend. Unlike the solution we designed previously for mounting the LGX on the CR-6 SE, here the extruder is firmly attached to the hotend to avoid the need of a gap on the PTFE tube. The need for a stable and reliable PTFE tube implementation is. The weight of the extruder is not a base for this design. There is no function to enable by dropping the hotend or extruder. For levelling the bed, the printer needs to press the nozzle against the bed and lift the strain gauge. The CR-10 version has a much shorter offset, because it can. The CR-6 requires a longer neck due to the x-carriage plate height. The offset is not caused by any pivoting requirement. The perch design is different from the CR-6 to the CR-10. Point 4 of the “How to set it up” section. It is a design option and we use it plenty. They are light, small, strong, resistant to twist, provide a good pressure surface to weight ratio. I have a bit more availability now to go deeper into our choices and answer your questions. Perhaps there is more meaning to the design not written. But, I’d like to hear why these were in the design decision. I think I’ll tweak this to remove the pivot and square nut in the end. I can see that, and that design aspect should remain.Īnyhow, thanks for the designs. I am guessing this is needed due to the extra weight now of the entire extruder and motor at the top. With the overhang over the outside of the load cell, this design does not allow any “downward pressure” to trigger the load cell (like the double-washers from the previous guide). In other words, there is no ability for the LGX Lite Mounting Plate to flex, or pivot, or even move from the Hotend Mount Plate because the extruder is rigidly mounted to the overall setup, allowing only upward movement. This Hotend Mount Plate is rigidly mounted ontop of the load cell using the screws that rigidly connects the hotend. I do not understand this design, nor does this article go into detail of why there is such an odd “offset” for this “pivot” design, or from what I can only guess is an attempt to pivot.įrom where the LGX Lite attaches to the LGX Lite Mounting Plate perch firmly connects to the Hotend Mount Plate. …with a single screw, offset, in a tight-fitting hole. On this guide, instead, we are printing a “perch” for the LGX Lite to sit on… Hence, the unique double-washer setup you had on the previous guide. I understand from the previous LGX CR-6 guide that we do not want the extruder triggering the load cell during extrusion. I still need to figure out something about the JST-6 connector on the CR-6’s original wiring harness… I guess, worse case, just cut, strip, solder, heat shrink and be done? Eh…ģ. But hopefully LDO is more careful about color codes. I know I know, wire coloring doesn’t mean anything with steppers. Personally, I am going to try to identify the wire coloring on the LDO site. However, there is no such cable available for purchase here – and, I see the older connectors have been discontinued on your site? The previous LGX guide for the CR-6 had an JST-6 to JST-6 extension cable available for purchase. There are no instructions about wiring up the LGX Lite’s wiring harness (with 4-pin connector) to the CR-6 SE nor CR-10 Smart. There is zero reason for a square nut here.Ģ. If I have the time, I’ll tweak the STEP to allow just a regular M3 nut. I am going to drill it out and install a heatset insert instead as I happen to have plenty of those. But, a square nut?!? There’s even more surface area on a regular nut than a square nut, if we are going for twisting strength! The LGX Lite Mounting Plate: Why in the world would you ever require a “square” M3 nut? No one has those with 3D printers! We are drowning in T-nuts (which could have been used), as well as regular nuts (which also could have been used with an indention). Thank you for providing the STEP and License so, I can make the changes. However… A few problems with this design. I was going to start designing my own, and then the newsletter in my mailbox today made me very happy. What great timing as I have just finished printing everything else LGX + CR6 from the other article, where I was awaiting this adapter in this article for the LGX Lite.
