UPDATE: 2023-07-01
Hi Snapmaker Owners with the Dual Extrusion Module,
I have great news to share with you! After a thorough analysis, testing, and observation, we have identified effective solutions for the heat dissipation and buckle loosening issues with the Dual Extrusion Module. We’d like to update you on our latest plan.
We are currently preparing a replacement kit specifically targeting the reported issues. While the occurrence of each problem may vary, we aim to provide a convenient solution for the users who require it. The replacement kit consists of four different components, each addressing a specific issue:
- Silicone Buckle Wedge for the Dual Extrusion Module - Fixing the popping feeder levers.
- Front Cover for the Dual Extrusion Module - Optimizing cooling airflow with the improved design.
- Spare part for the Dual Extrusion Module filament sensor - Reducing wear on the trigger lever to prevent false alarms.
- Silicone Bed Shims (0.5 mm thick) for the Artisan 3D Printing Platform - Resolving incomplete contact in some machines during the leveling process.
Considering the traditional support service process where users have to contact our Support team for troubleshooting and arranging the delivery of replacement parts, it usually takes about a week. This time, we want to improve the efficiency of users obtaining replacement parts and resolving their issues. Therefore, we plan to make the replacement pack available for self-ordering on our official online store.
To show our appreciation, we will be providing all existing customers with a one-time free coupon for the replacement kit. When using this coupon, our loyal customers can enjoy a zero-cost purchase, waiving the additional logistics fee. However, due to the high logistics cost of international express shipping from Shenzhen, China, we plan to prepare the replacement kit in bulk and ship it to our overseas warehouse via sea freight. Once the pack arrives at the warehouse, it will be made available on our official online store. At that time, we will send out the replacement pack coupons and provide more information through official emails to our existing customers.
Please note that the replacement pack is only necessary if you encounter the specific issues we mentioned above. Otherwise, if the machine is functioning normally, we do not recommend users to replace any parts.
Regarding the timeframe, we are in the process of preparing the materials for the replacement kit and plan to ship it by sea freight in mid-July. As an example, for customers in the United States, we estimate that the replacement pack will arrive at the overseas warehouse by mid-August and be delivered to users in late August. The sea freight time to Europe is expected to be around two weeks longer than to the United States. However, customers in China will receive the replacement pack earlier, as their logistics time only takes one to two days. We will closely monitor user feedback regarding the replacement parts and promptly share updates in the community.
Once again, we appreciate your understanding and support! If you have any questions, please feel free to leave a comment on this topic.
Make Something Wonderful.
Original Post
Dear Snapmaker 3D printer owners,
We have received feedback that some of our users have experienced issues with the extruder buckle breaking loose during printing, which results in a failed extrusion of the filament. We understand that this can be a frustrating issue and wanted to provide a temporary solution while we prepare a long-term one.
Previously, we shared a solution to this problem through our Wiki, which seems to have led to some confusion. To avoid such confusion in the future, we have decided to share temporary solutions in the community and permanent ones on the Wiki site.
As a quick solution for those currently experiencing this issue, we’ve designed a Buckle Wedge model file.
Steps:
- IF both extruders are experiencing this problem and unable to print, insert a plastic block (3 mm thick) between the buckle as illustrated, making it able to print first.
- Download the wedge model file below and print it out with PLA or TPU.
buckle wedge.stl - IF you’ve inserted a block in Step 1, remove it now.
- Insert the wedge between the buckle as illustrated to increase the clamping force and prevent the buckle from breaking loose.
I want to emphasize that this is a temporary solution. We have prepared silicone pads with adhesive backing that can be placed inside the buckle to keep it sufficiently elastic, allowing for continued printing. Once it’s available, we’ll update the community.
Lastly, we want to thank you for your patience and understanding. As always, we value your feedback and would love to hear back from you about your experience with this solution and any suggestions you may have.
